a. construct a multiple regression model for this problem. what is the estimated regression function?
b. interpret the value of the r2 statistic for this model.
c. construct an approximate 95% prediction interval for the expected selling price of an 18-inch diameter casserole pan. interpret this interval.
d. what other variables not included in the model might explain the remaining variation in auction selling prices for these items?
