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 58%?

0.21

0.42

0.58

0.79

0.42

Step-by-step explanation:

When finding the margin of error for the mean of a normally distributed population from a sample, the critical probability, assuming a confidence level of 58% is 0.42;

100 - 58 = 42%

= 0.42

The critical probability is simply the area of the critical region;

α, The probability of Type I error
