A set of test scores is normally distributed with a mean of 70 and a standard deviation of 8. Use the 68-95-99.7 rule to find the percentage of scores in each of the following categories:

• greater than 78
• between 70 and 86

Round to one decimal places if needed. You do not need to put the % sign in your answer.
