A regression model to predictY, the state burglary rate per 100,000 people for 2005, used the following four state predictors:X₁= median age in 2005,X₂= number of 2005 bankruptcies,X₃= 2004 federal expenditures per capita (aleadingpredictor), andX₄= 2005 high school graduation percentage.

(a)Fill in the values in the table given here for a two-tailed test at= 0.01 with 45 d.f.(Negative values should be indicated by a minus sign. Leave no cells blank - be certain to enter "0" wherever required.Round your t-values to 3 decimal places and p-values to4 decimal places.)
