Check my work mode : This show O A regression model to predict Y, the state-by-state 2005 burglary crime rate per 100,000 people, used the following four state predictors X, = median age in 2005, X2 = number of 2005 bankruptcies per 1,000 people, X, = 2004 federal expenditures per capita. and XA = 2005 high school graduation percentage. point Predictor Coefficient Intercept 4,414.1682 AgeMed -25.674 Bankrupt 17.8059 FedSpend -0.0313 HSGradx 30.1905 (a) Write the fitted regression equation.
