Question

We want to examine the relationship between body temperature and heart

rate X. Further, we would like to use heart rate to predict the body temperature.

  • Use an appropriate test to test the hypothesis H0: p=0, where p is the population correlation.
  • Use the above data set to build a simple linear regression model for body temperature using heart rate as the predictor.
  • Interpret the estimate of regression coefficient and examine its statistical significance.
  • Find the 95% confidence interval for the regression coefficient.
  • Find the value of R2 and show that its relationship with the sample correlation coefficient.
