A statistics professor is curious if class example references can impact test grades. She's read that interesting topics are associated with greater engagement from students, and might influence memory. Thus, she decides to modify her class examples to include interesting pop-culture references. After the class is finished, she finds that her class of 35 students obtains an average grade of 78. Assuming a population mean of 74 and a standard deviation 9, use the four steps of hypothesis testing with an alpha of 0.05 and a two-tailed test, to test the hypothesis that pop-culture references can have an impact on test grades. Based on this information, answer the following questions using the appropriate hypothesis test. What is the appropriate hypothesis test? z-test OR t-test Step #1: State the Null (Ho) and Alternative (H1) Hypotheses Ho : HPsychology = OR =/= UPop-Culture H1 : MPsychology = OR =/= MPop-Culture
