_ Colorful Tile, Inc., is a rapidly growing chain of ceramic tile outlets that caters to the do -yourself home remodeling market. In 2020, 33 stores were operated in small to medium-size metropolitan markets. An inhouse study of sales by these outlets revealed the following (standard errors or standard deviations are in parentheses) Q=45P+2A +0.ZI+0.25HF (3) (1.8) (0.7) (0.1) (0.1) R2 = 0.93, standard error of the estimate (SEE) = 6 Here, Q is tile sales (in thousands of cases), P is tile price (per case), A is advertising expenditures (in thousands of dollars), I is disposable income per household (in thousands of dollars), and HF is household formation (in hundreds). (A)Fully evaluate and interpret these empirical results on an overall basis using R3, adjusted R], and F statistic. (B) Which regression analysis problem might apply to this regression estimate? Why? (C) Which independent variables are statistically signicant at the 95% condence level? (D) Is quantity demanded sensitive to own price (1')? (E) Austin, Texas, was a typical market covered by this analysis. During 2020 in the Austin market, price (1') was $5, advertising (A) was $30,000, income (I) was an average $55,000 per household, and the number of household formations (HF) was 4000. Calculate and interpret the relevant advertising point elasticity. (F) Given the values of the independent variables in part E above, give a point estimate and an interval estimate of Q with 95% condence level. (G) Assume that the preceding model and data are relevant for the coming period. Estimate the probability that the Austin store will make a prot during 2021 if total costs are projected to he $300000
