The agronomist believed that the amount of rainfall as well as the amount of fertilizer used would affect the crop yield. She did the experiment in the following way. Thirty greenhouses were rented. In each, the amount of fertilizer and the amount of water were varied. At the end of the growing season, the amount of corn was recorded. Use ?=0.05
a) Determine the sample regression line and interpret the coefficients
b) Do these data allow us to infer that there is a linear relationship between the amount of fertilizer and the crop yield?
c) Do these data allow us to infer that there is a linear relationship between the amount of water and the crop yield?
d) What can you say about the fit of the multiple regression model?
e) Is it reasonable to believe that the error variable is normally distributed with constant variance (Support your answer)?

Five pairs of data are used in determining a regression line ŷ = -3 + 4x. If the five values of the
explanatory variable are 28, 45, 16, 41, and 20, respectively, what is the mean of the five values of the
response variable?
