b. Calculate a point estimate of the median of the coating thickness distribution, and state which estimator you used. c. Calculate a point estimate of the value that separates the largest 10% of all values in the thickness distribution from the remaining 90%, and state which estimator you used. [Hint: Express what you are trying to estimate in terms of m and s.]
d. Estimate P(X < 1.5), i.e., the proportion of all thickness values less than 1.5. [Hint: If you knew the values of m and s, you could calculate this probability. These values are not available, but they can be estimated.]
e. What is the estimated standard error of the estimator that you used in part (b)?
The coating thickness distribution is normal and has a mean value of 1.245.
What is mean?In statistics, in addition to the mode and median, the mean is one of the measures of central tendency. Simply put, the mean is the average of the values in the given set. It indicates that values in a particular data set are distributed equally. The three most frequently employed measures of central tendency are the mean, median, and mode.
To calculate the data's coating thickness, sample mean is employed.
The following formula is used to determine the mean value's point estimate:
[tex]\bar x = \frac{1}{n} \sum x_i[/tex]

The probability that the card is a face card (i.e., a jack, queen, or king) or a heart is 8/13
In the given question, suppose that you draw a card from a standard deck of cards.
We have to find the probability that the card is a face card (i.e., a jack, queen, or king) or a heart.
As we know that in a deck of cards have total 52 cards.
In which 26 cards are in heart shape.
Every different type of card have 3 face cards and have total four different type of cards. That means there are total 12 face cards.
In 26 cards of heart have total 6 face cards.
So, the probability that the card is a face card (i.e., a jack, queen, or king) or a heart
P = (Total face cards + total heart shape card - 6 face cards)/Total cards in a deck
P = (12 + 26 - 6)/52
P = (38 - 6)/52
P = 32/52
P = 8/13
Hence, the probability that the card is a face card (i.e., a jack, queen, or king) or a heart is 8/13.

2. A slow-moving bug is climbing a 15 ft. pole to reach a critical food source. It manages to climb 3
each day, but at night it slides back down 1 ft. How many days will it take the bug to reach the top and
get the food?
Step-by-step explanation:
a0 = 0 ft (starting on the ground)
a1 = a0 + 3 - 1 = a0 + 2
an = an-1 + 3 - 1 if an-1 +3 < 15
an = an-1 + 3 if an-1 + 3 >= 15
so, we need to find the n, so that
an = an-1 + 2 >= 12
but by looking at the structure, we see that every step just adds 2 ft to the total height.
an = a0 + 2n = 0 + 2n = 2n
2n >= 12
n >= 6
so, with day 6 the bug reaches 12 ft height. in day 7 it gets up to 15 ft and reached its goal.
it will take 7 days for the bug to reach the top and get the food.

A cloud is drifting across the sky at 552metersperminute. it is at an altitude of 9,200 meters. if its speed remains steady, how far will the cloud move in 17.5minutes?
The cloud can ascend 9,616 metres in 17.5 minutes, based on the statement made.
How is altitude measured and what does it mean?Utilizing the measurement of air pressure, altitude may be calculated. The pressure decreases with increasing altitude. An instrument is referred to as a pressure analyzer or pneumatic altimeter when a barometer is given a nonlinear calibration to display altitude.
This may be calculated by dividing the cloud's speed (552 metres per minutes) by the distance it must travel (17.5 minutes). We now know the distance to be 9,616 meters.
The speed of said cloud and the length of time it is going are four pieces of information that must be known in order to determine the minimum distance the cloud might cover in 17.5 minutes. We must increase the cloud's stated speed of 552 meters a minute by the distance it is going across, which in itself is 17.5 minutes. As a result, we now have 9,616 meters overall.
Another way to see this is to picture the cloud beginning at place A (9,200 meters) or terminating at point B. (9,616 meters). The distance between points A and B will be covered in 17.5 minutes if the cloud is moving at a pace of 552 meters per minute.

Points A, B, C, D, E, F and G are on a number line such that B, C, D, E and F divide segment AG into 6 equal pieces. If A is at 13 and G is at 59, what is the sum of the numbers at B, C, D, E and F
The sum of numbers at B, C, D, E and F is 110.5
Since B, C, D, E, and F divide the segment AG into 6 equal pieces, each piece has a length of (59-13)/6 = 6.5.
Therefore, the numbers at B, C, D, E, and F are located at 13 + 6.5, 13 + 6.52, 13 + 6.53, 13 + 6.54, and 13 + 6.55 respectively.
The sum of the numbers at B, C, D, E and F is (13 + 6.5) + (13 + 6.52) + (13 + 6.53) + (13 + 6.54) + (13 + 6.55)
= 13 + 6.5*(1+2+3+4+5) = 13 + 6.5*15 = 13 + 97.5

A cell phone plan cost $27.70 per month for 500 minutes of talk time. It cost an additional $0.08 per minute for each minute over 500 minutes. To get email access, it cost 30% of the price for 500 minutes of talk time. Your bill, which includes email, is the same each month for 9 months. The total cost for all 9 months is $367.29. Write and solve an equation to find the number of minutes of talk time you use each month.
Answer:
567 minutes each month.
Step-by-step explanation:
Let x be the number of minutes of talk time used each month.
The cost for talk time beyond 500 minutes is $0.08 * (x - 500)
The cost for email is $27.70 * 0.3 = $8.31
The total monthly cost is $27.70 + $0.08 * (x - 500) + $8.31 = $35.99
The total cost for 9 months is $35.99 * 9 = $323.91
So we can set up the equation:
$27.70 + $0.08 * (x - 500) + $8.31 * 9 = $367.29
Solving for x, we get:
x = 567
So the number of minutes of talk time used each month is 567 minutes.
a gym class has $12$ students, $6$ girls and $6$ boys. the teacher has $4$ jerseys in each of $3$ colors to mark $3$ teams for a soccer tournament. if the teacher wants at least one girl and at least one boy on each team, how many ways can he give out the jerseys? (jerseys of the same color are indistinguishable.)
So, the teacher can give out the jerseys in 840 ways.
The teacher wants to divide the 12 students into 3 teams, each with at least one girl and one boy.
One possible way to count the number of ways to divide the students is to use the stars and bars method.
For the first team, we have 5 stars and 2 bars, so the number of ways to pick 6 students is:
(5+2)!/(5!2!) = 7
For the second team, we have 4 stars and 1 bar, so the number of ways to pick 6 students is:
(4+1)!/(4!1!) = 5
For the third team, we have 3 stars, so the number of ways to pick 6 students is:
(3+0)!/(3!0!) = 4
Then we can multiply the number of ways to pick students for each team together to find the total number of ways to divide the students:
7 * 5 * 4 = 140
Then, as the jerseys are indistinguishable, we just have to multiply the number of ways to divide the students by the number of ways to distribute jerseys:
140 * 3! = 840
Therefore, the teacher can give out the jerseys in 840 ways.

We know that the total number of clementines is 180, Sal brought 4 bags and Joe brought 6. To determine how many bags Trisha brought, we need to determine the total number of bags that Sal and Joe brought together. We can do this by combining the two numbers together (4 + 6). This will give us a total of 10 bags. To determine how many bags Trisha brought, we need to subtract the total number of bags that Sal and Joe brought (10) from the total number of clementines (180). This gives us an answer of 170. This means that Trisha brought 170 clementines, or 7 bags. Therefore, the equation to determine how many bags Trisha brought is: T = 180 - (4 + 6).

5x+6=7x-6
Please help
Answer:
x = 6
Step-by-step explanation:
5x+6=7x-6
-6 -6
--------------------
5x = 7x - 12
-7x -7x
--------------------
-2x = -12
------------
-2 -2
--------------------
x = 6
Answer:
6
Step-by-step explanation:
first we combine like terms
6+6=7x-5x
then we simplify
12=2x
lastly we divide both sides by 2
2x ÷2=12÷2
an we simplify again
x=6
then the value of x is 6
check
5(6)+6=7(6)-6
30+6=42-6
36=36
ASSUME THAT 13% OF PEOPLE ARE LEFTHANDED, IF WE RANDOMLY SELECT 12 PEOPLE FROM THIS POPULATION, WHAT IS THE PROBABILITY THAT THEY ARE NOT ALL RIGHT HANDED
It is simpler to compute the likelihood of the complement event when calculating probabilities since you can then just subtract it from 1 to determine the probability.
What do probability and example mean?the variety of strategies for success. all events that could possibly occur.
Since 13% of people are lefties and 87% are righties, we'll assume that everyone is either a righty or a lefty, thus the decimal percentage of 0.87 divided by the total number of participants, 12, is the mean.
P(Right handed) = 1 - 0.13 = 0.87 where P(Left handed) = 0.13 and P(Right handed) = 0.13 12 people make up the nth number. The binomial probability distribution will be used in this case, and it can be computed using the formula P(X = n|N,p) = NCn*(pn)*(1-p) (N-n).
where p is the chance of success and n is the sample size, or 12, in this case. Additionally, q represents the 0.13 failure chance.
