that there is a positive relationship between the number of building permits

issued and the amount of work available to his company. Now he wonders if it is

possible to use knowledge of interest rates on first mortgages to predict the

number of building permits that will be issued each month. You collect a random

sample of nine months of data, as shown in Table P-11

e. Compute the coefficient of determination.

f. Write a sentence that Ed can understand, interpreting the

number computed in part e.
