Suppose that the amount of change, in dollars, in a WWU student's pocket is exponentially distributed with a mean of $0.27.

If you randomly sample 40 WCC students, what is the probability that the mean amount of change in their pockets is more than $0.27 ?

In other words,

if X represents the random variable for the amount of change in an individual WCC student's pocket,

and if X is exponentially distributed with a mean equal to 0.27,

then what is P(X>0.27) equal to?
