Essay

The temperatures on randomly chosen days during a summer class and the number of absences from class on those days are listed below. Calculate Spearman's rank correlation coefficient. Can you conclude that there is a correlation between the temperature and the number absent? Use $\alpha = 0.01$ $$\begin{array} { l | l l l l l l l l l } \text { Temp } & 62 & 75 & 81 & 80 & 78 & 88 & 65 & 90 & 70 \\\hline \text { Absences } & 16 & 20 & 23 & 23 & 21 & 28 & 17 & 28 & 18\end{array}$$
