Essay

The data below are the ages and systolic blood pressures (measured in millimeters of mercury)of 9 randomly
selected adults. Test the significance of the correlation coefficient using α $\alpha$ = 0.05 and the claim ρ $\varrho = 0 \text {. }$ $$\begin{array} { l | c | c | c | c | c | c | c | c | c | } \text { Age, } \mathrm { x } & 43 & 46 & 50 & 53 & 56 & 58 & 62 & 66 & 70 \\\hline \text { Pressure, } \mathrm { y } & 114 & 118 & 121 & 129 & 140 & 143 & 146 & 148 & 150\end{array}$$
