The MINITAB output given in Figure 8.39 is based on fitting a simple linear regression model relating hip circumference (????) to thigh circumference (????) using the data in the Body Fat data set (???? = 252). Use the information in figure 8.39 to answer the following questions.

(a) Estimate the mean value of Hip when Thigh= 60.

(b) Compute a 95% confidence interval for the mean hip circumference of an adult male with a thigh circumference of 60 cm.

(c) Compute the value of the prediction error for predicting the value of hip circumference for an adult male with a thigh circumference of 60 cm.

(d) Compute a 95% prediction interval for the hip circumference of an adult male with a thigh circumference of 60 cm.
