The researchers also hypothesized that the mean relational intimacy score for participants in the CMC group would significantly increase between the first and third meetings, but the difference between the first and third meetings would not significantly change for participants in the FTF group.
a. For the CMC group comparison, give the null and alternative hypotheses of interest.
b. The researchers made the comparison, part a, using a paired t-test. Explain why the data should be analyzed as matched pairs.
c. For the CMC group comparison, the reported test statistic was t = 3.04 with p-value = .003. Interpret these results. Is the researchers' hypothesis supported?
d. For the FTF group comparison, give the null and alternative hypotheses of interest.
e. For the FTF group comparison, the reported test statistic was t = .39 with p-value = .70. Interpret these results. Is the researchers' hypothesis supported?
