According to the National Weather Service, the mean daily temperature in Fort Pierce is 72.9, F with a standard deviation of 3.9 F. Consider the mean daily temperature in Fort Pierce for a sample of 47 randomly selected days. Determine the probability that the mean daily temperature of a sample of 47 randomly selected days is greater than the mean daily temperature by at least 1.3 F. Round the solution to four decimal places, if necessary. P( greater than by at least 1.3 F)
