Table B. 2 presents data collected during a solar energy project at Georgia Tech.

a. Fit a simple linear regression model relating total heat flux $y$ (kilowatts) to the radial deflection of the deflected rays $x_{4}$ (milliradians).

b. Construct the analysis-of-variance table and test for significance of regression.

c. Find a $99 %$ CI on the slope.

d. Calculate $R^{2}$.

e. Find a $95 %$ CI on the mean heat flux when the radial deflection is milliradians.
