A consumer research organization will evaluate the results of two diet programs,Take-It-Off and Melt-Away.Persons are randomly sampled from each of the programs and their weight loss results follow. $$\begin{array} { | c | c | } \hline \text { Take-It- Off } & \text { Melt-Away } \\\hline 150 & 130 \\75 & 68 \\40 & 20 \\68 & 54 \\30 & 27 \\& 98 \\\hline\end{array}$$
-The test question is: Do the data indicate that the two programs are equally effective? What is the calculated test statistic W?
