Assume that a random variable is normally distributed with a mean of 24 and a standard deviation of 2. Consider an interval of length one unit that starts at the value a so that the interval is [a, a + 1]. For what value of a is the probability of the interval greatest? Does the standard deviation affect that choice of interval?

ANSWER:Step 1 of 2
Given,
The mean,
The standard deviations,
Consider X as a normal random variable with mean 24 and standard deviation 2, the random variable
is a normal random variable with E(Z) = 0 and V(Z) = 1. That is, Z is a standard normal random variable.
