Running a mile. The times for the mile run of a large group of male college students are approximately Normal with mean 7.11 minutes and standard deviation 0.74 minutes. Use the 68-95-99.7 rule to answer:
a.) What range of times covers almost all (99.7%) of this distribution?
b.) What percent of these men run a mile in less than 6.37 minutes?
This is a homework problem and I would love to know the answer as well as how to figure it out. I cannot understand this!
