The value of a sports franchise is directly related to the amount of revenue that a franchise can generate. The data below gives the value and the annual revenue for 15 major sport teams. The data are modeled by the equation Y₁ = -1032.3098 +7.6853X;, where X; is the annual revenue and Ỹ; is the predicted value for the ith franchise. Perform a residual analysis for these data. Based on these results, evaluate whether the assumptions of regression have been seriously violated. Click the icon to view the table of franchise value and annual revenue. ... Which of the assumptions of regression, if any, have been seriously violated? Select all that apply. A. The assumption of linearity has been violated because the data are clearly curvilinear. B. The assumption of independence has been violated because errors from later time periods appear to be related to those from earlier time periods. C. The assumption of equal variance has been violated because the variability of the residuals is much greater when the annual revenue is smaller. D. The assumption of normality has been violated because the normal probability plot does not appear to be a straight line. E. The assumptions of linearity, independence, normality, and equal variance do not appear to have been seriously violated.
