Following are measurements of tensile strength in $ksi(x)$ and Brinell hardness (y) for 10 specimens of cold drawn copper. Assume that tensile strength and Brinell hardness follow a bivariate normal distribution. 2 a) Find a $95\%$ confidence interval for $?$, the population correlation between tensile strength and Brinell hardness. b) Can you conclude that $?<0.3$ ? c) Can you conclude that $??=0$ ?
