Suppose a random sample of 10 fish are selected from a lake and weighed. Suppose further that the standard deviation of weights for fish in the lake is 1 lb.

Suppose the number of fish randomly sampled from the lake were increased to 100. What would be the probability that this sample would produce a sample mean of 3.2 or larger, if the mean weight of all the fish in the lake remained at 3.0? (Use the TI calculator or Excel file - Normal for x-bar to compute the probability.)
