The mean percent of childhood asthma prevalence in 43 cities is 2.09%. A random sample of 32 of these cities is selected. What is the probability that the mean childhood asthma prevalence for the sample is greater than 2.5%? Interpret this probability. Assume that σ = 1.32%. The probability is (Round to four decimal places as needed.)

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 800 gas stations, the mean price for regular gasoline at the pump was $2.857 per gallon and the standard deviation was $0.008 per gallon. A random sample of size 60 is drawn from this population. What is the probability that the mean price per gallon is less than $2.855? The probability that the mean price per gallon is less than $2.855 is (Round to four decimal places as needed.)
