Consider the accompanying set of dependent and independent variables. The variable x3 is qualitative with H=?High, M=?Medium, and L=Low. Complete parts a and b below.

Consider the accompanying set of dependent and independent variables. The variable x3 is qualitative with H = High, M = Medium, and L = Low. Complete parts a and b below. a. Using technology, construct a regression model using all three independent variables. (Let variable Condi be one of the dummy variables for x3. Assign a 1 to High for this variable. Let Cond2 be another dummy variable for x3. Assign a 1 to Medium for Click the icon to view the set of variables. this variable.) Complete the regression equation for the model below, where x3 represents the dummy variable Cond1, and x4 represents the dummy variable Cond2. - X y =0+ (0) * + (0) *2+ (0)*3 + ()*4 Variables (Round to three decimal places as needed.) 15 73 56 47 34 25 20 70 65 30 27 26 15 11 y 41 41 * 1 50 38 35 16 15 64 76 52 46 45 76 M M H H L H M L L Print Done
