The peanut crop was harvested from five fields of various area. The following data are the mass of the crop from each field y (in kilograms) and the field area x (in hectares).y 7480 15530 13400 20070 12950x 2.26 3.72 3.61 4.02 2.84Required:a. Fit the simple linear regression model using the method of least squares. Find the estimate of ^2.b. What change in the mean mass is expected when the field area changes by 1 hectare?c. Calculate the fitted value of y corresponding to x = 2.26. Find the corresponding residual. d. Estimate the mean mass of the crop harvested from 2.5 hectares.
