5. Suppose we examine the factors that determine the abortion rate across the 50 states in the USA with the following variables; - - Abortion = Abortion rate, number of abortions per thousand women aged 15-44 in 1992. Religion = the percent of a state's population that is Catholic Price = the average price charged for an abortion Laws = a variable that takes the value of 1 if a state enforces a law that restricts abortion, 0 otherwise. Funds = a variable that takes the value of 1 if state funds are available for use to pay for an abortion, 0 otherwise. Educ = the percent of a state's population that is 25 years or older with a high school degree (or equivalent). Income disposable income per capita, 1992. Picket = the percentage of respondents that reported experiencing picketing The regression results with 50 observations are reported below; reg abortion religion price laws funds educ income picket Source SS df MS Model Residual 2862.66338 2094.96246 7 408.951912 42 49.8800585 Total 4957.62584 49 101.176038 Number of obs F(7, 42) Prob > F R-squared Adj R-squared Root MSE 50 8.20 0.0000 = 0.5774 0.5070 7.0626 abortion Coef.
