Answer 1

You should avoid posting personal information on the internet. That being said, you can use z scores. The z score is how many standard deviations a value is from the mean. In this case, it would be:\[\frac{64.2-59}{6.7}=\frac{5.2}{6.7}\approx 0.77\]

Knowing how many standard deviations past the mean you are can tell how much area is to the left of 59 by using a z table.
