Ideal height of your mate. Refer to the Chance (Summer 2008) study of the height of the ideal mate, Exercise 11.33 (p. 629). The data were used to fit the simple linear regression model, E1y2 = b0 + b1x, where y = ideal partner’s height (in inches) and x = student’s height (in LO9 

inches).

a. Fit the straight-line model to the data for the male students.

Find an estimate for s, the standard deviation of the error term, and interpret its value practically.

b. Repeat part a for the female students.

c. For which group, males or females, is student’s height the more accurate predictor of ideal partner’s height?
