We believe that gender might also be related to body temperature and could help us to predict its unknown values.
(a) Use the “BodyTemperature.txt” data set to build a multiple linear regression model for body temperature using heart rate and gender as predictors.
(b) How much R 2 did increase compared the above simple linear regression model?
(c) Explain the estimates of regression coefficients in plain language.
(d) Find the 95% confidence intervals for regression coefficients.
(e) If a woman’s heart rate is 75, what would be your estimate of her body temperature? What would be your estimate of body temperature for a man whose heart rate is 75.
