Using the given regression equation: y = 156.31 + 2.915x1 + 57.77x2 + 69.06x3 + 21.27x4 Substituting x1 = 10, and x2 = x3 = x4 = 0 (because they are not given in the problem): y = 156.31 + 2.915(10) + 57.77(0) + 69.06(0) + 21.27(0) y = 156.31 + 29.15 y = 185.46 Therefore, the predicted value of y for x₁ = 10 is 185.46 or 2,535.86 (rounded to two decimal places). So, option E is correct.
