Simple Linear Regression & Correlation REG2a

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) Calculate the regression line, y=ax+b.
 2) Calculate 95% confidence interval of regression coefficient and assess the statistical significance of the regression.
 3) Show the 95% confidence interval range of estimated y values at given x values on the graph.
