Final answer:
A 4.25% increase in sales per share from the 2003 figure of $525, leading to an estimated sales per share of approximately $547. The closest option provided is $550 (option b).
Step-by-step explanation:
To estimate the industry sales per share for the year 2004 for the U.S. Autoparts Industry, we'll use the provided regression analysis. The analysis shows that the change in industry sales per share (%D Sales per share) is a function of the change in personal consumption expenditures (%D PCE) with a given formula of %D Sales per share = 0.02 + 1.5(%D PCE).
The personal consumption expenditures (PCE) are expected to grow by 1.5% in 2004. Applying this growth rate of 1.5% to the regression formula gives us: %D Sales per share = 0.02 + 1.5(1.5%) = 0.02 + 1.5 * 0.015 = 0.02 + 0.0225 = 0.0425 or 4.25%.
To find the actual sales per share for the year 2004, we take the previous year's sales per share which is $525 and increase it by the percentage change: $525 * (1 + 0.0425) = $525 * 1.0425 = $547.3125.
Thus, when rounded to nearest dollar, the estimated sales per share for the year 2004 is $547. Looking closely, the answer that matches this calculation is not directly listed, so we would have to choose the closest given option which is $550 (option b).
