The model E(y) = β0 + β1x1 + β2x2 + β3x3 + β4x4 was used to relate E(y) to a single qualitative variable, where

x1 =   x2 =  
x3 =   x4 =  
   
This model was fit to n = 40 data points and the following result was obtained:

= 14.5 + 3x1 - 4x2 + 10x3 + 8x4

a.Use the least squares prediction equation to find the estimate of E(y) for each level of the
qualitative variable.
b.Specify the null and alternative hypothesis you would use to test whether E(y) is the same for
all levels of the independent variable.
