question 104

Essay

For the data below, test the significance of the correlation coefficient using α $\alpha$ = 0.01 and the claim ρ $Q = 0$ $$\begin{array} { c | c | c | c | c | c | c | c | c | c | c | } \mathrm { x } & - 13 & - 11 & - 4 & - 7 & - 9 & - 10 & - 8 & - 6 & - 5 & - 12 \\\hline \mathrm { y } & 5 & 0 & - 12 & - 7 & - 3 & - 2 & - 5 & - 10 & - 11 & 2\end{array}$$
