Question 1065713: Assume that a normal distribution of data has a mean of 17 and a standard deviation of 2. Use the 68−95−99.7 rule to find the percentage of values that lie above 13.
What percentage of values lie above 13​?

That would be the percentage more than 2 sd below the mean, or more than 13.
2.5% are more than 2 sd below the mean by the empirical rule.
Therefore everything else is above 13, or 97.5%.
