In Problem 14.7 on page 584, you used the total staff present and remote hours to predict standby hours (stored in Standby). Use the results from that problem.
a. Determine whether there is a significant relationship between standby hours and the two independent variables (total staff present and remote hours) at the 0.05 level of significance.
b. Interpret the meaning of the p-value.
c. Compute the coefficient of multiple determination, r2, and interpret its meaning.
d. Compute the adjusted r2.
In problem
Standby hours (Y)-Total number of standby hours in a week
Total staff present (X1) - Weekly total of people-days
Remote hours (X2) - Total number of hours worked by employees at locations away from the central plant
Data were collected for 26 weeks; these data are organized and stored in Standby.
