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%?

To find the margin of error for the mean of a normally distributed population from a sample, the critical probability, , is obtained by

where p is the confidence level.

Assuming a confidence level of 86%, the critical probability is given by

Ithink the answer is c just trying to others

This is a robot. try again lol. maybe you attached the wrong image.
