The data file HappyMarried.sav contains data gathered by the General Social Survey given in 2004. It includes ratings of happiness measured on a scale of 1-3 where 1 = very happy, 2 = pretty happy, and 3 = not too happy. The file also identifies the marital status of each participant. Determine if the distribution of happiness ratings of married people ( marital = 1) differs from that of the never married people ( marital = 5).
