a. Interpret the group means for lower- and upper-class respondents. Which attends church more often? group b. Assume alpha = .05 for a two-tailed test. What can you conclude about the difference in church attendance between the two groups? %3D c. If alpha were changed to .01, would your Step 5 decision change? Explain.

.404 Equal variances not assumed IMMEDIATÉ FÁMILY C12. Based on the 2018 GSS, we compare church attendance (ATTEND) between lower and upper-class respondents. ATTEND is an ordinal measure: 0 = never, 1 = less than once a year, 2 = once a year, 3 = several times a year, 4 = once a month, 5 = 2–3 times a month, and 6 = nearly every week.
