A real estate software program gives the estimated values of homes and lists characteristics of the homes. A prospective home buyer used the program to collect a sample of twenty-five homes and recorded the estimated value of the homes and how many bathrooms they contain. The prospective home buyer wants to investigate whether there is an association between the number of bathrooms a home contains and the estimated value of the home. Assuming all conditions for inference are met, which of the following significance tests should be used for the investigation? A. A two-sample z -test for a difference between proportions

B. A linear regression t -test for slope

C. A matched pairs t -test for a mean difference

D. A two-sample t -test for a difference between means

E. A chi-square test of independence
