Step 2 of 3 :
Using the model from the previous step, predict the company’s revenue for the 15th month. Round to four decimal places, if necessary.
NOTE:
Sum of X = 105Sum of Y = 9756Mean X =Mx = 7.5Mean Y=My = 696.8571Sum of squares (SSX) = 227.5Sum of products (SP) = 8132Regression Equation = ŷ = b0 + b1Xb1 = SP/SSX = 8132/227.5 = 35.74505b0 = MY - b1MX = 696.86 - (35.75*7.5) = 428.76923ŷ = 428.7692 + 35.7451X
Hence the regression equation is ;
Revenue = 428.7692 + 35.7451 (Month ) ( answer)
