question 36

Essay

These data are listed below. $$\begin{array} { | c | c | c | } \hline \text { Book } & \text { Number of pages } & \text { Selling price } ( \$ ) \\\hline 1 & 844 & 55 \\\hline 2 & 727 & 50 \\\hline 3 & 360 & 35 \\\hline 4 & 915 & 60 \\\hline 5 & 295 & 30 \\\hline 6 & 706 & 50 \\\hline 7 & 410 & 40 \\\hline 8 & 905 & 53 \\\hline 9 & 1058 & 65 \\\hline 10 & 865 & 54 \\\hline 11 & 677 & 42 \\\hline 12 & 912 & 58 \\\hline\end{array}$$ Can we infer at the 5% significance level that the editor is correct?
