Problem 13.8 presented per capita expenditures on education for 15 large Canadian cities, along with rank on income per capita and the percentage of the population that has graduated from high school. The data are reproduced below. Take educational expenditures as the dependent variable.

 a. Compute beta-weights for each independent variable and compare their relative effect on expenditures. Which is the more important factor?

 b. Compute R and R².

 c. Write a paragraph summarizing your findings.

 Problem 13.8

The table below presents the scores of 15 large Canadian cities on three variables. Compute r and r²
for each combination of variables. Assume that these 15 cities are a random sample of Canada’s 50 largest cities and test the correlations for their significance. Write a paragraph interpreting the relationships among these three variables.
