He has collected a random sample of 17 low-end condos that have sold within the past three months. Complete parts a through c below. Use a 99% confidence level where needed. Click the icon to view the data table. a. Develop a simple linear regression model to explain the variation in selling price based on the number of weeks the condo is on the market. The regression equation is y = 58635.51 + (941.74 )x. (Round to two decimal places as needed.) b. Test to determine whether the regression slope coefficient is significantly different from 0 using a significance level equal to 0.01. What are the correct hypotheses to test? OA. HO: B1 = 0 OB.
