A survey is conducted on attitudes towards drinking. A random sample of eight married couples is selected, and the husbands and wives respond to an attitude-toward-drinking scale. The scores are as follows: Husbands Wives 16 15 20 18 10 13 15 10 8 12 19 16 14 11 15 12 a) What would be the hypotheses for this scenario? Calculate the estimated standard deviation for this scenario. b) Compute the standard error of the difference for these samples. c) What is the test statistic and at an alpha level of .05 what conclusions would you make about the null hypothesis?
