Using simple regression, determine whether test scores are
significantly related to sales performance. Use significance level
of 0.05%. Clearly interpret the slope (beta coefficient) and the
adjusted R squared value you obtained.
Using multiple regression, determine whether test scores and
number of months are significantly related to sales performance.
Use significance level of 0.05%. Clearly interpret the slopes (beta
coefficients) and the adjusted R squared value you obtained.
