The accompanying data are the shoe sizes and heights (in inches) of 14 men. Find the equation of the regression line. Then construct a scatter plot of the data and draw the regression line. Then
use the regression equation to predict the value of y for each of the given x-values, if meaningful. If the x-value is not meaningful to predict the value of y, explain why not.
(a) x = 11.5
(b)x=8.0
(c) x = 15.5
(d) x = 10.0

(a) Predict the height for a shoe size of 11.5, if it is meaningful. Select the correct choice below and, if necessary, fill in the answer box within your choice.
O A. y = in. (Round to two decimal places as needed.)
OB. It is not meaningful to predict this value of y because x = 11.5 is not an x-value in the original data.
OC. It is not meaningful to predict this value of y because x = 11.5 is inside the range of the original data.
(b) Predict the height for a shoe size of 8.0, if it is meaningful. Select the correct choice below and, if necessary, fill in the answer box within your choice.
OA. y=
in. (Round to two decimal places as needed.)
OB.
It is not meaningful to predict this value of v because x = 8.0 is well outside the range of the original data.
