Answer:

Step-by-step explanation:

Is there enough evidence to reject the researcher claim?

To determine if there is enough evidence to reject the researcher's claim, we can perform a hypothesis test with a null hypothesis of p <= 0.05 (at most 5% of working college students are employed as teachers or teaching assistants) and an alternative hypothesis of p > 0.05 (more than 5% of working college students are employed as teachers or teaching assistants).

Find the critical values and identify the rejection.

For a one-tailed test with a significance level of alpha = 0.05, the critical value for a z-test would be 1.645. This means that if the calculated z-score is greater than 1.645, we would reject the null hypothesis.

Find the standardized test statistic z

To find the standardized test statistic z, we can use the formula:

z = (p-hat - p0) / (sqrt(p0 * (1 - p0) / n))

where p-hat is the sample proportion of working college students employed as teachers or teaching assistants (6%), p0 is the proportion specified in the null hypothesis (5%), and n is the sample size (400).

z = (0.06 - 0.05) / sqrt(0.05 * (1 - 0.05) / 400)

z = 0.1 / 0.015811388300841898

z = 6.317

Decide whether to reject or fail to reject the null hypothesis and interpret the decision.

Since the calculated z-score (6.317) is greater than the critical value (1.645), we can reject the null hypothesis. This means that there is enough evidence

The p-value of the test hypothesis for each case is given as follows:

b) n = 9: 0.1151.

i. n = 25: 0.0228.

ii. n = 100: 0.

iii. When the sample size increases, the test statistic also increases, and hence the p-value decreases.

Before obtaining the p-value, the first step is obtaining the test statistic for the test.

The z-distribution is used, as the standard deviation for the population is known, and the equation is given as follows:

[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which the parameters are given as follows:

The fixed parameters for this problem are given as follows:

[tex]\overline{x} = 52, \mu = 50, \sigma = 5[/tex]

Hence, for n = 9, the test statistic is given as follows:

z = (52 - 50)/(5/3)

z = 1.2.

We have a right-tailed test, as we are testing if the mean is greater than a value, hence the p-value is of 1 subtracted by the p-value of z = 1.2, that is:

1 - 0.8849 = 0.1151.

With n = 25, we have that:

z = (52 - 50)/(5/5)

z = 2.

z = 2 has a p-value of 0.9772.

1 - 0.9772 = 0.0228.

With n = 100, we have that:

z = (52 - 50)/(5/10)

z = 4.

z = 4 has a p-value of 1.

1 - 1 = 0.

Overview

To answer the question given, we have to find the point on the line that goes through the points given in the table when the x-axis represents the month of the year (1 is Jan, 2 is Feb, etc.) and the y-axis represents the average temperature for that month.

Method 1

I've attached a graph of the line for reference.

When we look at the graph of the line that goes through the points given in the table, we can determine that its y-intercept is (0, 28).

Method 2

To determine the y-intercept of the line without actually graphing it, we can construct an equation using the given points.

We know that the line's slope is defined as [tex]\dfrac{\textrm{rise}}{\textrm{run}}[/tex].

Using that information, we can solve for the line's slope by using any two of the given points. I will use the points for January (1, 42) and February (2, 56).

[tex]\textrm{slope} = \dfrac{56-42}{2-1} = \dfrac{14}{1} = 14[/tex]

Then, we can plug this value into the point-slope form equation

[tex]y - b = m(x - a)[/tex]

along with one of the given points [tex](a,b)[/tex] -- I'll use January (1, 42):

[tex]y-42=14(x-1)[/tex]

Next, to solve for the y-coordinate of the line's y-intercept, we can plug 0 into the equation for x and solve for y.

[tex]y - 42 = 14(0 - 1)[/tex]

[tex]y - 42 = 14(-1)[/tex]

[tex]y - 42 = -14[/tex]

[tex]y = -14 + 42[/tex]

[tex]y = 28[/tex]

Finally, we can plug the solved y-coordinate and 0 for the x-value (because we solved for when y when x = 0) into the format of a Cartesian coordinate:

The periodic fixed costs of the company, based on the cost function, are $1,000.

The fixed costs refer to the period costs that do not change in total concerning the production or activity level and they relate to a financial period.

The fixed cost per unit decreases as more units are produced and vice versa.  However, within the relevant range, the fixed cost for the period remains the same.

A cost function is a model or formula that shows the total costs based on different cost behaviors (fixed and variable) and the relationship of costs to the production quantity.

Cost functions can be used to predict the total costs to be incurred under different production levels.

In this situation, the cost function, C = 1000 + 3.75q, shows that the fixed cost per period is $1,000 and $3.75 per unit (variable).

Thus, based on the cost function, the fixed costs are $1,000.

The cafe served 49 regular coffees.

You can use the proportion of regular coffees to the total number of coffees to find out how many regular coffees were served.

If 70% of the coffees served were regular, that means that 100-70 = 30% of the coffees served were decaffeinated.

To find out how many regular coffees were served, you can use the following proportion:

(Number of regular coffees) / (Total number of coffees) = 70% / 100%

You can then cross-multiply and solve for the number of regular coffees:

Number of regular coffees = (70/100) * (Total number of coffees)

Given the Total number of coffees = 70, you can substitute that and get:

Number of regular coffees = (70/100) * 70 = 49
