Assume that a normal distribution of data has a mean of 15 and a standard deviation of 2 Use the 68-95-99.7 rule to find the percentage of values that lie below 11. what percent of values lie below 11?

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.
