(Solution Download) The probability of a value between 7 0 and 13 0 drawn

The probability of a value between 7.0 and 13.0 drawn from a normal distribution with mean 10.0 and variance 4.0.
Use the cumulative distribution function for the standard normal, ?(z), to find the above probabilities. Shade the associated area on two graphs: the given normal distribution, and the standard normal distribution.
