(a) Write the fitted regression equation. (Round your answers to 4 decimal places. Negative values should be indicated by a minus sign.) yy^ = + AgeMed + Bankrupt + FedSpend + HSGrad% (b-1) The 2005 state-by-state crime rate per 100,000

multiple choice 2

  • increases by about 26 as the state median age increases.
  • decreases by about 26 as the state median age increases.

(b-2) The 2005 state-by-state crime rate per 100,000 multiple choice 4

  • increases by about 17 for every 1,000 new bankruptcies filed.
  • decreases by about 17 for every 1,000 new bankruptcies filed.

(b-3) The 2005 state-by-state crime rate per 100,000 multiple choice 6

  • increases by 0.0161 for each dollar increase in federal funding per person.
  • decreases by 0.0161 for each dollar increase in federal funding per person.

(b-4) The 2005 state-by-state crime rate per 100,000 multiple choice 8

  • decreases by about 31 for each 1% increase in high school graduations.
  • increases by about 31 for each 1% increase in high school graduations.

(c) Would the intercept seem to have meaning in this regression? multiple choice 10

  • Yes
  • No

(d) Make a prediction for Burglary when X1 = 34 years, X2 = 7.9 bankruptcies per 1,000, X3 = $7,959, and X4 = 89 percent. (Round your answers to 4 decimal places.) Burglary Rate $
