Suppose you will perform a test to determine whether there is sufficient evidence to support a claim of a linear
correlation between two variables. Find the critical values of r given the number of pairs of data n and the significance
level $\alpha$
-The regression equation relating attitude rating $( x )$ and job performance rating $( y )$ for the employees of a company is $\hat{ y} = 11.7 + 1.02 x$. Ten pairs of data were used to obtain the equation. The same data yield $r = 0.863$ and $\bar { y } = 80.1$. What is the best predicted job performance rating for a person whose attitude rating is 73 ?
A) $80.1$
B) $12.6$
C) $84.9$
D) $86.2$
