A set of data is normally distributed with a mean of 64 and a standard deviation of 2.5. What percent of the data is in the interval 64-66.5?

The chunk of data described is the region between the mean and one standard deviation to the right of the mean. Based on a normal distribution, approximately 34% of all the data should fall within that range
