Question

eBook The exercise involving data in this and subsequent sections were designed to be solved using Excel. In a regression analysis involving 30 observations, the following estimated regression equation was obtained. Enter negative values as negative numbers ý = 17.6 +3.8æ1 - 2.3x2 + 7.6x3 + 2.7x4 a. Interpret b1, b2, b3, and b4 in this estimated regression equation. Assume that for each coefficient statement, the remaining three variables are held constant (to 1 decimal). b= estimated change in y per 1 unit change in 1 y per 1 unit change in 2 estimated change estimated change unit change in X3 y per estimated change in y per 1 unit change in t4 b. Estimate y when = 10, X2 = 5, x3 = 1, and 4 = 2. (to 1 decimal)
