a.Develop the least squares estimated regression equation.
b.At 95% confidence, perform a t test and determine whether or not the slope is significantly different from zero.
c.Perform an F test to determine whether or not the model is significant. Let = 0.05.
d.Compute the coefficient of determination.
e.Compute the coefficient of correlation.
