Question

The following data apply to a few questions below. Assume that the average price for a gallon of gas in the US is $3.73 and the equivalent of $3.40 in Russia. (It was in March 2012.) Assume these figures are the population means (not a sample) and that the distributions can be described as a normal distribution. The σ = $0.25 in the US and σ = $0.20 in Russia.

- What is the probability that a randomly selected gas station in the US charges less than $3.50?
- What percentage of gas stations in Russia charge less than $3.50?
- What is the probability that a randomly selected gas station in Russia charged more than the mean price in the US?

Answer #1

Suppose that the price of a gallon of gasoline is normally
distributed with a mean of 3.73 dollars and a standard deviation of
0.25 dollars. What is the probability that a gas station charges
less than or equal to 3.50 dollars per gallon?
Use the information from Question 3. What is the probability
that a gas station charges between 3.25 and 4 dollars per
gallon?
