In Chapters 4 and 6 we’ve seen data from the Hopkins Forest. Here’s a regression that models the maximum daily wind speed in terms of the average temperature and precipitation: 

a) Write the regression model.
b) What is the interpretation of the coefficient of Precip?
Here is the partial regression plot for the coefficient of Precip in the regression:

c) What is the slope of the least squares regression line in the partial regression plot?
d) The point plotted with an “x” is for 8/28/2011—the date of Hurricane Irene. If we were to remove it from the data, what would happen to the coefficient of Precip?
