Let us hypothesize (imagine) that the number of automobile accidents in a certain region are related to the regional number of registered automobiles in thousands (b1), alcoholic beverage sales in $10,000 (62), and change in the price of gasoline in cents (b3). Furthermore, imagine that the regression formula has been calculated as: Y = a + b1X1 + b2x2+b3X3 where Y = the number of automobile accidents, a = 7.5, b1 = 3.5,b2 = 4.5, and b3 = 2.5 Predict the expected number of automobile accidents under the following conditions: X1 - 3 X2 = 5 X3 = 1 28 43 22.5 10.5 31
