Exercise:
Body temperature measurements by mercury thermometer were compared with those taken by electric thermometer in 14 pediatric hospitalized patients. Results are show below.
1) Plot the data as a scatter of points representing a pair of X and Y values.
2) Calculate the simple linear regression equation by the method of least squares.
3) Test the significance of the regression using analysis of variance procedure.
H0: The slope (β) =0
HA: The slope (β) ≠0
4) Calculate confidence Intervals for the regression coefficient.
5) Estimate, with 95% confidence, the value of x with a specified value of y.
6) Depict 95% confidence interval of Y estimate.
7) Predict the value of y at a specified value of x, inversely.
