Consider the following set of dependent and independent variables. The variable x3 is qualitative with M = Male and F = Female. The quantitative data for this problem can be found in the Excel file Prob 1534.xlsx.

y 10 11 15 15 20 24 27 32 x1 2 5 5 9 7 11 16 20 x2 16 10 13 10 2 8 7 4 x3 M M F F F M F F

a. Using PHStat, construct a regression model using all three independent variables.

b. Interpret the meaning of each of the regression coefficients.
