Question

The computer output shown below is part of the regression analysis to predict the height of the gold medal winning high jump in the Olympics based on year and gender (coded as males=0, females=1). Predictor Coef SE Coef T p Constant -9.0965 0.4708 -19.32 0.000 Year 0.0057426 0.0002409 23.84 0.000 Gender -0.34761 0.01537 0.000 Source DF SS MS F р Regression 2 2. 0735 1.0368 0.000 Error 42 0. 1015 0.0024 Total 44 2.1751 What is the regression equation?

Height = 0.4708 + 0.0002409 yr + 0.01537 gender

height = -9.0965 + 0.4708 yr -19.32 gender

height = 2. 0735 + 0. 1015 yr + 2.1751 gender

height = -9.0965 + 0.0057426 yr +-0.34761 gender

Answer 1

Solution: From the given problem the regression equation is| Height = -9.0965 + 0.0057426(Year) - 0.34761(Gender) Correct option is
