can someone please explain how to solve for these questions

The Minitab Regression Output for this problem is shown below. Regression Analysis: mileage versus weight (g) When performing a hypothesis test of H_0: beta_1 = 0 versus H_1: beta_1 notequalto 0 using alpha = 0.01, which of the following is the correct conclusion? Enter your response in Akindi answer form number 21. A. Fail to reject H_0 B. Reject H_0 C. Cannot determine from the information provided (h) When performing a lack of fit (LOF) test: H_0: Model is adequate(no LOF) versus H_1 LOF present using alpha = 0.01, which of the following is the correct conclusion? Enter your response in the Akindi answer form number 22. A. Fail to reject H_0 B. Reject H_0 C. Cannot determine from the information provided

Explanation / Answer

We will Compare P value to the significance level and then we decide whether to reject the null hypothesis or not

(g) Here P value of this test is 0.001 (check the P value of the Weight row given at the top) , since this value is less than 0.01, we reject the null hypothesis

Option B is correct

(h) Here P value of this test is 0.001 (check the P value of the Regression row in the ANNOVA Table ) , since this value is less than 0.01, we reject the null hypothesis

Option B is correct
