Determine if the finite correction factor should be used. If so, use it in your calculations when you find the probability.   In a sample of 700 gas stations, the mean price for regular gasoline at the pump was $2.876 per gallon and the standard deviation was $0.008 per gallon. A random sample of size 45 is drawn from this population. What is the probability that the mean price per gallon is less than $2.874?   The probability that the mean price per gallon is less than $2.874 is (Round to four decimal places as needed.)
