Q1. Suppose you wish to test the hypothesis that the number of print media (newspaper, magazine,
and so forth) that people subscribe to is related to subscribersâ€™ education levels. The following
hypothetical data was gathered from five people.
Number of subscriptions, x Education level, y (years)
(1) Draw a scatter diagram.
(2) Formulate null and research hypotheses that can be tested adequately using a correlation
H0: ______________________________________ (p=0)
H1: ______________________________________ (p=0)
(3) If the computed t value is in the rejection region (r=.97, p<.05), can you reject the null hypothesis at the p<.05 level of significance? Why? Show your work for t test.
Q2. Design a media effects study for which a correlation analysis is appropriate.
Then, provide the following information to conduct the study.
