Multiple Choice: Select the best answer for Exercises 87-92. Exercises 87-92 refer to the following setting. To see if stu- dents with longer feet tend to be taller, a random sample of 25 students was selected from a large high school. For each student, x = foot length (cm) and y = height (cm) were recorded. We checked that the conditions for infer- ence about the slope of the population regression line are met. Here is a portion of the computer output from a least- squares regression analysis using these data: Predictor Constant Foot length S 6.47044 Coef SE Coef T P 0.000 91.9766 10.2204 8.999 3.0867 0.4117 7.498 0.000 R-Sq=72.8% R-Sq (adj) = 71.5%

88. The slope 3 of the population regression line describes (a) the exact increase in height (cm) for students at this high school when foot length increases by 1 cm. (b) the average increase in foot length (cm) for students at this high school when height increases by 1 cm. (c) the average increase in height (cm) for students at this high school when foot length increases by 1 cm. (d) the average increase in foot length (cm) for students in the sample when height increases by 1 cm. (e) the average increase in height (cm) for students in the sample when foot length increases by 1 cm.
