Colorful Tile, Inc., is a rapidly growing chain of ceramic tile outlets that caters to the do-it-yourself home remodeling market. In 2020, 33 stores were operated in small to medium-size metropolitan markets. An in-house study of sales by these outlets revealed the following (standard errors or standard deviations are in parentheses) Q = 4 – 5P+ 2A + 0.21 + 0.25HF (3) (1.8) (0.7) (0.1) (0.1) R² = 0.93, standard error of the estimate (SEE) = 6 Austin, Texas, was a typical market covered by this analysis. During 2020 in the Austin market, price (P) was $5, advertising (A) was $30,000, income (I) was an average S55,000 per household, and the number of household formations (HF) was 4000. Calculate and interpret the relevant advertising point elasticity. 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). 2 Given the values of the independent variables in part E above, give a point estimate and an interval estimate of Q with 95% confidence level. Assume that the preceding model and data are relevant for the coming period. Estimate the 30 probability that the Austin store will make a profit during 2021 if total costs are projected to be $300000.

1 Austin, Texas, was a typical market covered by this analysis. During 2020 in the Austin
market, price (P) 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.
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).
