There is particular concern for obtaining the most efficient estimate of the relationship between income and house price. The company has collected data on their sales experience over the past years, and the data are contained in the attached table. Complete parts a though d below. Click the icon to view the data. Click the icon to view the upper critical values of the chi-square distribution. a. Estimate the regression of house price on family income. House Price = |+ (Family Income) (Round to two decimal places as needed.) Based on the graph, does it appear that there is heteroscedasticity in the regression errors? A. Yes, there is evidence of heteroscedasticity in the regression errors. B. No, there is no evidence of heteroscedasticity in the regression errors. c. Use a formal test of hypothesis to check for heteroscedasticity. Test at the 5% significance level. Determine the critical value, X1,a. X3,a =(Round to three decimal places as needed.) Determine the test statistic for this test for heteroscedasticity. I(Round to three decimal places as needed.) d. If you establish that there is heteroscedasticity in (b) and (c), perform another regression that corrects for heteroscedasticity. O A. yi yi (Round to two decimal places as needed.) O B. There is no heteroscedasticity
