Regular-grade gasoline prices for all the gas stations in Lee County have a normal distribution with a mean of $2.95 and
standard deviation of $0.16. Use this information and the standard Normal distribution to answer the next two questions.
What proportion of gas stations will charge more than $3.15 per gallon?
A manager of a discount gas station wants to set the price for gasoline at his station where only 10% of the stations in
Lee County will charge less than his price? What price should he charge for gasoline at his station?
I have been staring at this question for way too long. I cannot figure out the correct answer to this because I only know how to do it when I am given a population.
