Question

For a standard normal curve find the z-value with 1010% of the data to the right of it. Round your answer to two decimal places.

Answer 1

I would typically go to the invNorm function on a TI calculator for this problem, but I'm getting a domain error since probability is always between 0 and 1. Are you sure this question is supposed to read "1010% of the data"? The most area that can be under a standard normal curve (or any distribution, for that matter) is 100%, since that would account for 100% of the data. Is it possible to eat 1010% of a single pie in front of you, and we're only considering/limited to that one pie?
