- 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 .
