The probability of one robot succeeding in a task less than or equal to 80 times out of 100 can be calculated using a binomial distribution formula. Assuming the probability of success for one robot is p, the probability of success for both robots is p^2. Using the binomial distribution formula, we can calculate the probability of success for each robot and then multiply them together to find the probability of both robots succeeding less than or equal to 80 times out of 100. The formula is P(X<=80) = sum of P(X=k) from k=0 to k=80, where X is the number of successes in 100 attempts.

To calculate the probability of both robots succeeding less than or equal to 80 times out of 100, we need to first find the probability of success for one robot. Let's assume the probability of success for one robot is p = 0.7. The probability of success for both robots is then p^2 = 0.7^2 = 0.49.

Next, we need to use the binomial distribution formula to calculate the probability of success for each robot. The formula is P(X=k) = (n choose k) * p^k * (1-p)^(n-k), where n is the number of attempts, k is the number of successes, and (n choose k) is the binomial coefficient.

Using this formula, we can calculate the probability of one robot succeeding less than or equal to 80 times out of 100. P(X<=80) = sum of P(X=k) from k=0 to k=80 = sum of [(100 choose k) * 0.7^k * 0.3^(100-k)] from k=0 to k=80.

We can use a calculator or a software program like Excel to calculate this sum. The result is 0.9899, which means the probability of one robot succeeding less than or equal to 80 times out of 100 is almost 99%.

To find the probability of both robots succeeding less than or equal to 80 times out of 100, we just need to multiply the probability of one robot succeeding by itself: 0.9899 * 0.9899 = 0.9799. So the probability of both robots succeeding less than or equal to 80 times out of 100 is about 98%.

The probability of both robots succeeding less than or equal to 80 times out of 100 can be calculated using the binomial distribution formula. Assuming the probability of success for one robot is p, the probability of success for both robots is p^2. Using the formula P(X<=80) = sum of P(X=k) from k=0 to k=80, we can calculate the probability of one robot succeeding less than or equal to 80 times out of 100. Multiplying this probability by itself gives us the probability of both robots succeeding less than or equal to 80 times out of 100. For the given values, the probability is about 98%.

a.  P(X ≤ 2) = 0.77

b.  P(X = 1 or X = 2) = 0.60

c.  P(X > 0) = 0.83

d. The cumulative probability distribution function for X is given in the table.

(a) The probability of a randomly selected student holding two or fewer jobs during the past year is given by the sum of the probabilities of holding 0, 1, or 2 jobs:

P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.17 + 0.35 + 0.25 = 0.77

Therefore, P(X ≤ 2) = 0.77.

(b) The probability of a randomly selected student holding either one or two jobs during the past year is given by the sum of the probabilities of holding 1 or 2 jobs:

P(X = 1 or X = 2) = P(X = 1) + P(X = 2) = 0.35 + 0.25 = 0.60

Therefore, P = 0.60.

(c) The probability of a randomly selected student holding at least one job during the past year is the complement of the probability of holding no jobs:

P(X > 0) = 1 - P(X = 0) = 1 - 0.17 = 0.83

Therefore, P(X > 0) = 0.83.

(d) The cumulative probability distribution function for X is the sum of the probabilities up to and including the value k:

The correct answer is option A, "smoothing constant".

What is statistics?

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of numerical data.

Exponential smoothing is a widely used forecasting technique that involves giving different weights to the past observations in a time series, with the most recent observation being given the highest weight. The parameter that determines the weight given to the most recent observation is known as the "smoothing constant".

The smoothing constant is a value between 0 and 1, and it represents the rate at which the influence of past observations on the forecast decreases over time. A larger value for the smoothing constant gives more weight to recent observations, while a smaller value gives more weight to older observations.

The parameter of the exponential smoothing model that provides the weight given to the most recent time series value in the calculation of the forecast value is known as the "smoothing constant".

The critical value of z for a two-tailed test at 12.66% significance level is approximately ±1.88.

For a two-tailed test at 12.66% significance level, we need to find the critical value of z. Here are the steps to find the critical value:

1. Since it is a two-tailed test, we need to divide the significance level by 2. This is because the rejection region is distributed equally in both tails of the distribution. So, 12.66% ÷ 2 = 6.33%.

2. Now, we need to convert the percentage to a decimal: 6.33% = 0.0633.

3. Next, we need to find the z-score that corresponds to the given probability (0.0633) in the standard normal distribution table. To do this, look for the closest probability value to 0.0633 in the body of the table.

4. After finding the closest probability value, locate the corresponding z-score. For a two-tailed test, you will have both a positive and negative z-score, which are symmetric around the mean (0).

After following these steps, you will find that the critical value of z for a two-tailed test at 12.66% significance level is approximately ±1.88.

The variance is approximately 177.5 and the standard deviation is approximately 13.32.

The standard deviation (SD, also written as the Greek symbol sigma or the Latin letter s) is a statistic that is used to express how much a group of data values vary from one another.

To find the variance and standard deviation of the data set {91, 101, 75, 90, 88, 87, 90, 60}, we first need to find the mean:

mean = (91 + 101 + 75 + 90 + 88 + 87 + 90 + 60) / 8 = 85.5

Next, we need to calculate the deviation of each data point from the mean:

91 - 85.5 = 5.5

101 - 85.5 = 15.5

75 - 85.5 = -10.5

90 - 85.5 = 4.5

88 - 85.5 = 2.5

87 - 85.5 = 1.5

90 - 85.5 = 4.5

60 - 85.5 = -25.5

Then, we square each deviation:

5.5² = 30.25

15.5² = 240.25

(-10.5)² = 110.25

4.5² = 20.25

2.5² = 6.25

1.5² = 2.25

4.5² = 20.25

(-25.5)² = 650.25

The variance is the average of these squared deviations:

variance = (30.25 + 240.25 + 110.25 + 20.25 + 6.25 + 2.25 + 20.25 + 650.25) / 8 = 177.5

Finally, the standard deviation is the square root of the variance:

standard deviation = sqrt(variance) = √(177.5) = 13.32 (rounded to the nearest hundredth)

Therefore, the variance is approximately 177.5 and the standard deviation is approximately 13.32.

There is no outcome that satisfies this condition, while the product of the marginal probabilities is 4/16=1/4. Therefore, we conclude that x and y are not independent.

What is probability?

Probability is a measure of the likelihood of an event occurring. It is a numerical value between 0 and 1 (inclusive), where 0 represents an impossible event and 1 represents a certain event.

To show that x and y are not independent, we need to demonstrate that the joint probability distribution of x and y does not factor into the product of their marginal distributions.

The possible outcomes when two coins are flipped are:

HH

HT

TH

TT

Since the coins are fair, each of these outcomes has probability 1/4. We can define the random variables x and y as follows:

x is the number of heads, which can take on the values 0 or 1 or 2.

y is the number of tails, which can also take on the values 0 or 1 or 2.

The joint probability distribution of x and y can be represented by a 3x3 matrix:

[tex]\left[\begin{array}{ccc}1&0&0\\0&2&0\\0&0&1\end{array}\right][/tex]

The (i, j) entry of this matrix represents the probability that x=i and y=j. For example, the probability that x=1 and y=2 is 0, since there is only one outcome (HT) that satisfies this condition and its probability is 1/4.

The marginal distribution of x is obtained by summing the entries of each row:

x | 0 1 2

--|-----

p | 1 2 1

Similarly, the marginal distribution of y is obtained by summing the entries of each column:

y | 0 1 2

--|-----

p | 1 2 1

If x and y were independent, then the joint probability distribution would factor into the product of the marginal distributions:

[tex]\left[\begin{array}{ccc}p&p&p\\p&p&p\\p&p&p\end{array}\right][/tex]

However, this is not the case, as can be seen by comparing the joint probability distribution with the product of the marginal distributions. For example, the probability that x=1 and y=1 is 0, since there is no outcome that satisfies this condition, while the product of the marginal probabilities is 4/16=1/4.

Therefore, we conclude that x and y are not independent.

fave = (4/50) * [[tex]25^{(3/2)[/tex] - [tex]0^{(3/2)[/tex]]

fave = (4/50) * ([tex]25^{(3/2)[/tex])

fave = 10√25

fave = 10(5)

fave = 50

Therefore, the average value of the function [tex]f(x) = x^{(1/2)[/tex] on the interval [0, 25] is 50.

Answer: Type I error and Type II error are associated with hypothesis testing, where we test a hypothesis by collecting data and analyzing it.

For the given hypothesis, we can set up the null hypothesis as follows:

H0: The percentage of households with Internet access is less than or equal to 60%.

And the alternative hypothesis as:

Ha: The percentage of households with Internet access is greater than 60%.

Now, a Type I error occurs when we reject the null hypothesis (i.e., conclude that the percentage of households with Internet access is greater than 60%) when it is actually true. This means that we would be making a false claim that the percentage of households with Internet access is greater than 60%, when it is not.

On the other hand, a Type II error occurs when we fail to reject the null hypothesis (i.e., conclude that the percentage of households with Internet access is less than or equal to 60%) when it is actually false. This means that we would be missing the truth that the percentage of households with Internet access is greater than 60%.

So, in the context of the given hypothesis, a Type I error would be to conclude that the percentage of households with Internet access is greater than 60% when it is actually less than or equal to 60%, and a Type II error would be to fail to conclude that the percentage of households with Internet access is greater than 60% when it is actually greater than 60%.
