The data and MINITAB output from fitting a least squares regression line to the data are given in Table 13.3 on the next page.
a. Find the least squares point estimates b0 and b1 on the computer output and report their values.
b. Interpret b0 and b1. Does the interpretation of b0 make practical sense?
c. Write the equation of the least squares line.
d. Use the least squares line to compute a point estimate of the mean demand in all sales periods when the price difference is .10 and a point prediction of the demand in an individual sales period when the price difference is .10.
