How many dummy variables are required to represent the categorical variable? Consider the following regression equation relating x 1 and the categorical variable to y. E(y) = 0 + 1 x 1 + 2 x 2 + 3 x 3 Enter the values of dummy variables x 2 and x 3 that are used to indicate the three levels of the qualitative variable. Level x 2 x 3 1 Select Select 2 Select Select 3 Select Select Interpret the parameters in your regression equation. 1 is the change in E(y) to a 1 unit change in Select holding the categorical variable constant. 2 = Select 3 = Select

Here are the steps to factor the expression:
30x^3 + 35x^2 + 10x
5x(6x^2 + 7x + 2)
5x(6x^2 + 3x + 4x + 2)
5x(3x(2x + 1) + 2(2x + 1))
5x(3x + 2)(2x + 1)
