Question

The value of the t distribution with 14 degrees of freedom such that the area to the right of it is 0.025, i.e. t(14), is 2.14. What is the 95% confidence interval for the population slope?

Answer 1

the confidence interval would be:

 

coefficient value +/- 2.14*standard error of the estimator
