C13. In Chapter 7's SPSS Demonstration, we used the Explore command to calculate the confidence intervals for HRSRELAX for men and women. The GSS 2018 asked respondents "after an average work day, about how many hours do you have to relax or pursue the activities you enjoy?" In this exercise, we selected married GSS respondents and calculated the t test for HRSRELAX. a. Is there a significant difference between married men and married women in the number of hours they have to relax during the day? Set alpha at .05. b. If alpha was changed to .01, would your Step 5 decision change? Explain. Group Statistics Sed. Std.
