William
used a sample of 68 U.S. cities to estimate the relationship between
Crime (annual property crimes per 100,000 persons) and Income (median
income per capita). His estimated regression equation was Crime = 428 +
.050 Income.
Assuming b1 is significant, if Income decreases by 1000 we would predict that Crime will __________.
A. increase by 428
B. decrease by 50 C. increase by 500 D. increase by 50
