Solution 1

The correct answer is (X+2)/5.

Here's why:

A standard normal variate is a random variable that has been standardized to have a mean of 0 and a standard deviation of 1.

If X is normally distributed with a mean of -2 and a variance of 25, then the standard deviation is the square root of the vari Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
