Well, by definition, the standard deviation for the standard normal distribution is 1. So this is 1 right here. This is easier than I thought it would be. Part E. The percentage of data above 2. So they want the percentage of data above 2. So we know from the 68, 95, 99.7 rule that if we want to know how much data is within 2 standard deviations. So let me do it in a new color.
