Question

When finding the margin of error for the mean of a normally distributed population from a sample, what is the critical probability, assuming a confidence level of 86%?

Answer 1

To find the margin of error for the mean of a normally distributed population from a sample, the critical probability, $\alpha$, is obtained by
$p=1-\alpha$
where p is the confidence level.

Assuming a confidence level of 86%, the critical probability is given by
$\alpha =1-0.86=0.14$
