Suppose that 50% of a bank'saccounts are held by students and that 50% are held by people who are not college students. Let x represent the number of checks written in a given month by a randomly selected bank customer.(a) Give a sketch of what the population distribution of x might look like.(b) Suppose that the mean value of x is 21.0 and that the standard deviation is 16.7.
