Question: Refer to exercise 5. a. Use = .01 to test the hypotheses H0: 1 = 2 = 0 Ha: 1 and/or 2 is not

Refer to exercise 5.
a. Use α = .01 to test the hypotheses
H0: β1 = β2 = 0
Ha: β1 and/or β2 is not equal to zero
For the model y = β0 + β1x1 + β2x2 + ε, where
x1 = television advertising ($1000s)
x2 = newspaper advertising ($1000s)
b. Use α = .05 to test the significance of = 1. Should x1 be dropped from the model?
c. Use α = .05 to test the significance of = 2. Should x2 be dropped from the model?
