a. how many dummy variables are required to represent the categorical variable?
b. 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
c. enter the values of dummy variables x 2 and x 3 that are used to indicate the three levels of the qualitative variable.

x31 0 or (select 0 or 1) (select0 or 1) (select 0 or 1)
