Consider the following set of dependent and independent variables. These data can also be found in the Excel file Prob 153.xlsx.

y 47 42 40 40 31 26 23 18 10 x1 74 63 78 52 44 47 35 17 15 x2 22 29 20 17 13 17 8 15 10

a. Using PHStat, construct a regression model using both independent variables.

b. Test the significance of each independent variable using a = 0.10.

c. Interpret the p-value for each independent variable.
