American Institute of Pharmaceutical Technology Null and Alternative Hypothesis Sheet

### Question Description

I don’t understand this Excel question and need help to study.

I already did the problems I just need help stating the null and alternative. Attached is the requirements and the finished HW file.

1.Complete Problems 29 and 30

a. Question 29: Using the Excel file Facebook Survey, determine if the mean number of hours spent online per week is the same for males as it is for females.

b.﻿Question 30: Determine if there is evidence to conclude that the mean number of vacations taken by married individuals is less than the number taken by single/divorced individuals using the data in the Excel file Vacation Survey. Use a level of significance of 0.05. Would your conclusion change if the level of significance were 0.01?

§For each hypothesis test, state the null and alternative hypotheses.

§For each hypothesis test, state whether you would reject or not reject the null hypothesis.

§For each hypothesis test, interpret the conclusion of the test in context.

§For each hypothesis test, use the unequal variances procedure

2.Complete Problem 38

a.﻿Question 38: Using the data in the Excel file Ohio Education Performance, test the hypotheses that the mean difference in writing and reading scores is zero and that the mean difference in math and science scores is zero. Use the paired-sample procedure.

§State the null and alternative hypotheses.

§State whether you would reject or not reject the null hypothesis.

§Interpret the conclusion of the test in context.
