Question

The approximate​ Z-score that corresponds to a right tail area of 0.42 is what?

Answer 1

A right tail area of 0.42 means that we are looking at the area covered by 1- 0.42 = 0.58 from the left. From the standard probability distribution table, we located what is Z score at P = 0.58, hence the answer is:

Z score = 0.202
