Multiple Choice

Use the following information to answer the question. A random sample of 30 couples who were also new home owners were asked to report the cost of their first house and their combined age when they married. The output of a regression analysis for predicting home cost from combined age is shown. Assume that the conditions of the linear regression model are satisfied.

-Test the hypothesis that the slope is zero (significance level is 0.05) , then choose the correct decision regarding the null hypothesis and the statement that correctly summarizes the conclusion.

• A)Reject H0. We don't have enough evidence to reject a slope of zero which is an indication that no linear association exists between combined age of the couple and home cost.
• B)Reject H0. There is enough evidence to reject a slope of zero which is an indication that a linear association exists between combined age of the couple and home cost.
• C)Fail to reject H0. There is enough evidence to reject a slope of zero which is an indication that a linear association exists between combined age of the couple and home cost.
• D)Fail to reject H0. We don't have enough evidence to reject a slope of zero which is an indication that no linear association exists between combined age of the couple and home cost.
