Hout, Duncan, and Sobel (1987) reported on the relative sexual satisfaction of married couples.
They asked each member of 91 married couples to rate the degree to which they agreed with €œSex is fun for me and my partner€ on a four-point scale ranging from €œnever or occasionally€ to €œalmost always.€ The data appear below. (I know it€™s a lot of data, but it€™s an interesting question, and the data can always be downloaded from the book€™s website.)

Start out by running a matched-sample t test on these data. Why is a matched-sample test
appropriate?
