# Question: The computer output shown below is for predicting foot length

The computer output shown below is for predicting foot length from hand length (in cm) for a group of women. Assume the trend is linear. Summary statistics for the data are shown in the table below.

The regression equation is

y = 5.67 + 0.998 x

Pearson correlation of HandL and FootL = 0.948

a. Report the regression equation, using the words “Hand” and “Foot,” not x and y.

b. Verify the slope by using the formula b = r sy/sx.

c. Verify the y-intercept by using the formula a = y-bar – bx-bar.

d. Using the regression equation, predict the foot length (in cm) for someone who has a hand length of 18 cm.
