Question
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 %3D %3D 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. A lower score indicates lower church attendance. %3D %3D Group Statistics Subjective class identification Std. Deviation Std.

a. Interpret the group means for lower- and upper-class attends church more often? respondents. Which 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.
