Which of the following is the equation of the least-squares regression line for predicting height from foot length?

a.

b.

c.

d.

e.

To see if students 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 inference 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:

height = 10.2204 + 0.4117 (foot length)
