A made-up reading club records, for six members, the minutes spent reading one evening and the…

Step 1. Correct data. $\bar{x} = 22.5$ minutes and $\bar{y} = 13.5$ pages. $S_{xx} = 437.5$, $S_{yy} = 165.5$ and $S_{xy} = 267.5$. So $r = \dfrac{267.5}{\sqrt{437.5 \times 165.5}} = 0.9941$.

Step 2. Typed data. Now $\bar{y} = 10.33$ pages, $S_{yy} = 181.33$ and $S_{xy} = 30$. So $r = \dfrac{30}{\sqrt{437.5 \times 181.33}} = 0.1065$.
