Question

A one-sample ?-test (Could be EITHER a z- ort-test: complete by hand)

Oakland University performs a survey of students and learns the average number of hours spent studying per week across the population of all students is 14 hours a week, with a standard deviation of 3 hours. However, a random sample of current SOC 2020 students (N = 100) finds that the mean number of hours spent studying per week is 14.5. You want to know if SOC 2020 students are studying morethanthe entire population of OU students – is this half-hour difference statisticallysignificant?

1. What assumptions are you making about this data and the level of measurement of the variable you are interested in?

2. Hypotheses & alpha

1. State your nullhypothesis, both mathematically and in English:

2. State your researchhypothesis, both mathematically and in English:

3. Will this be a one- or two-tailed test? __________
4. What alpha would you use if you wanted to be 95% confident in your decision to reject or not reject the null hypothesis? __________

3. The test statistic and probability

1. Calculate the standard error, which will be used as the denominator of the test statistic equation. Be sure to include the basic equation and show your work:

2. Calculate the appropriate test statistic, using the standard error you just calculated as the denominator. Be sure to include the basic equation and show your work:

C. Using the appropriate Appendix in your textbook, explain how you would find the p-value associated with the test statistic you calculated.  What is the probability (P) associated with this test statistic value?
