Scenario (use this scenario for the next three questions):

Antônia is interested in the social media activity of Quinnipiac students. She predicts that QU students will use social media more than the typical college student in the population. She asks a sample of 75 QU students to report how many hours they spend on social media per week and finds that their mean number of hours is 9 (SD = 2.25). The data are normally distributed. She then looks up the national average for social media use among college students, and finds the following: μ = 9.15.

Question: Based on the information in this scenario (and after considering the assumptions of each test), which of the following statistical tests would be the most appropriate for testing Antônia's hypothesis?

a. Single-sample z test

b. Calculate z scores

c. Independent samples t test

d. Single-sample t test
