Assume the random variable x is normally distributed with mean μ=88 and standard deviation σ=4. Find the indicated probability. P(78<x<82)
Please leave a comment if there is any doubt. The use of the standard normal table was made to find the values of the standard normal CDF's.
Please leave an up vote if you like the solution............!!!!!!!!!!!!!!!!!!!!!!!
