The average number of mosquitos in a stagnant pond is 60 per square meter with a standard deviation of 12. If 16 square meters are chosen at random for a mosquito count, find the probability that the average of those counts is more than 63.0 mosquitos per square meter. Assume that the variable is normally distributed.
