Q2. The relationship of Outdoor temperature in degrees (X1) also the thickness of insulation in inches (X2) on monthly, electric heating costs in KWH (Y) is given by the regression equation Y' = 62.43 - 1.45 X1 - 0.52 X2. The Multiple Standard Error of the Estimate is 2.2 KWH. If a structure had 4 inches of insulation also the temperature was 62 degrees Illustrate what is the estimated KWH also illustrate what is the interval which would contain 95 percent of such estimates.
