11. A distribution center for a chain of electronics supply stores fills and ships
orders to retail outlets. A random sample of orders is selected as they are
received and the dollar amount of the order (in thousands of dollars) is recorded,
and then the time (in hours) required to fill the order and have it ready for
shipping is determined. A scatterplot showing the times as the response variable
and the dollar amounts (in thousands of dollars) as the predictor shows a linear
trend. The least squares regression line is determined to be: yˆ= 0.76 +1.8x. A plot
of the residuals versus the dollar amounts showed no pattern, and the following
values were reported: Correlation r + 0.90; R 2 = 0.81; standard deviation of the
residuals is 0.48. What percentage of the variation in the times required to
prepare an order for shipping is accounted for by the fitted line?
a) 48%
b) 81%
c) 90%
d) 76%
