Homework Answers
Answer:
We have to find out the critical t value,
We know the t distribution is the symmetric distribution.
We have to find 96% confidence that is at level of significance = 0.04 at 14 degrees of freedom.
Since, the t is symmetric distribution
Hence we check the value of 0.02 corresponding to 14 degrees of freedom is 2.264
Hence, the critical t value that corresponds to 96% confidence at 14 degrees of freedom is equal to 2.264
Add Answer to:
(d) Find the critical t-value that corresponds to 96% confidence. Assume 14 degrees of freedom. (Round...
