According to records, the amount of precipitation in a certain city on a November day has a mean of 0.10 inches, with a standard deviation of 0.06 inches. What is the probability that the mean daily precipitation will be 0.095 inches or more for a random sample of 40 November days (taken over many years)?
Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places.
Excel spreadsheet finds this probability when given the mean of one day and standard deviation.
