Question

For each of the following scenarios, simply state WHICH technique would be the most appropriate method to analyze the results.

Answer 1

Answer:

Below is the solution to the given points:

Step-by-step explanation:

For point a:

There have 30 overviews paired here and we'd like to analyze the mean studying time in the middle and final periods. It will employ a paired t-test. The difference (d) = mid - final

Hypotheses:

$H_o: \mu_d \geq 0\\\\H_a: \mu_d < 0$

For point b:

More than three variables should be examined here because ANOVA is employed in one method.

For point c:

This one Z test is used since we have the standard difference in population.

Hypotheses:

$H_o:\mu = 45\\\\ H_a:\mu\neq 45$

For point d:

Since not knowing the sample standard deviation, we will use an individual sample t-test.

Hypotheses:

$H_o: \mu = 45\\\\ H_a: \mu \neq 45$
