A Television Rating Wants to Determine Whether Married Couples Tend

Essay

A television rating wants to determine whether married couples tend to agree about the quality of the television shows they watch. Ten couples are asked to rate a particular comedy series on a 7-point scale where 1 = terrible and 7 = excellent. The results are shown below. $$\begin{array} { | l | l | l | l | l | l | l | l | l | l | l | } \hline \text { Husband's rating } & 3 & 6 & 6 & 5 & 4 & 5 & 7 & 4 & 5 & 5 \\\hline \text { Wife's rating } & 5 & 5 & 4 & 5 & 4 & 4 & 6 & 3 & 4 & 5 \\\hline\end{array}$$ Do these data provide sufficient evidence at the 5% significance level to conclude that the husband's and the wife's ratings are positively related?
