Below is a graph of a normal distribution with mean =μ5 and standard deviation =σ3. The shaded region represents the probability of obtaining a value from this distribution that is greater than 8.

Suppose X is normally distributed with a mean of 8 and a variance of 1. What is the probability that X is greater than 0 but less than 8? (Your answer should be correct to one decimal place, and you should be able to answer without the use of Normal tables.)
