The mean yearly snowfall for Boston over the past century is 44
inches, with a standard deviation of 19 inches. Assume that the
snowfall amounts are approximately normally distributed and all CLT
conditions hold. If 10 winters are selected at random, what is the
probability that they will have a mean snowfall amount of more than
48 inches? Use 5 non-zero decimal places in your calculations.
Round z-values to 2 decimal places.
