<PRE><B>Question 195845</B>
The weights of the fish in a certain lake are normally distributed with a mean of 12 lb and a standard deviation of 12. If 16 fish are randomly selected, what is the probability that the mean weight will be between 9.6 and 15.6 lb?
----------------
normalcdf(9.6,15.6,12,(12/sqrt(16)) = 0.6730
