Answer:
D. 2.33
Step-by-step explanation:
Hint- We have to use Inverse Normal Probability Distribution function. This function returns the x-value given the probability region to the left of the x-value.
We have to calculate the z score of the 99th percentile of a standard normal distribution curve.
i.e the value of probability less than z is given as 99th percentile or 0.99
Using inverse normal probability distribution function, we get
