Please answer problem 2 parts a-d

Problem 2 Consider the hypothesis test for regression model Y = Bo + BIX; ten, Ho : 81 =0 vs HA : B1 # 0 (a) We calculated the bj =9, and a 95% cutoff region for the empty model is from -5.5 to 5.5. Will you reject the null hypothesis? (b) We calculated the b1 =9, and a 95% cutoff region for the empty model is from -11 to 11, do you think this parameter has an effect or not? (c) The p-value is 0.55, will you reject the null hypothesis at 95% confidence level? (d) The p-value is 0.00021, will you choose this model over the empty model at 95% confidence level
