You can put this solution on YOUR website!
Let Z ~ N(0, 1). If P(Z > a) = 0.0099, what value must "a" have? Give your answer to 2 decimal places.
------
Find invNorm(0.0099) = -2.33
That is the z-value with a left tail = 0.0099
----
Your problem asks for the z-value with a right
tail of 0.0099.
Ans: +2.33
