An agent for a real estate company wanted to predict the monthly rent for apartments based on the size of the apartment. The data for a sample of 25 apartments is available below. Perform at test for the slope to determine if a significant linear relationship between the size and the rent exists. a. At the 0.05 level of significance, is there evidence of a linear relationship between the size of the apartment and the monthly rent? b. Construct a 95% confidence interval estimate of the population slope, B. E Click the icon to view the data. a. Determine the hypotheses for the test. Choose the correct answer below. O A. H B, =0 H B, #0 O. H =0 OB. H B, 20 H;: B, <0 OD. H B, s0 H B >0 Find the test statistic. tSTAT =U (Round to two decimal places as needed.) What is the p-value? p-value = (Round to three decimal places as needed.) Reach a decision. V Họ There is V evidence to conclude that there is a linear relationship between the size of the apartment and the monthly rent. b.
