A psychologist studying perceived “quality of life” in a large number of cities (N 5 150) came up with the following equation using mean temperature (Temp), median income in $1000 (Income), per capita expenditure on social services (Socser), and population density (Popul) as predictors.

3Y N = 5.37 2 0.01Temp 1 0.05Income 1 0.003Socser 2 0.01Popul

a.Interpret the regression equation in terms of the coefficients. b. Assume there is a city that has a mean temperature of 55 degrees, a median income of $12,000, spends $500 per capita on social services, and has a population density of 200 people per block. What is its predicted quality of life score? c. What would we predict in a different city that was identical in every way except that it spent $100 per capita on social services?
