Lieutenant Colonel Syl Verleaf is placed in charge of base security at all 240 mili-tary bases in Europe. Verleaf believes that the crime rate is positively correlated to the size of the base, the percentage of troops without high school degrees, and the number of women on base. Verleaf's statistician finds the following: where XI is the number of troops on the base, X2 is the percentage of troops with-out high school degrees, X3 is the number of women on the base, and Y is the number of serious crimes in a month. Interpret all the regression coefficients, R2 and the intercept. 'What is the most important independent variable? Ramstein Air Base has 15,000 troops, 42% of its troops have no high school degree, and there are 3,000 women on base. What is your best estimate of the number of crimes per month for this base?
