Suppose that the number of customers who enter a bank (X) in a minute is a Poisson random variable. WeknowthatP(X=1|){g1)=0.9 Let T be the time required to observe one customer arriving to the bank. The formula C=1DD+72T denotes the waiting cost (measured in money} incurred by a customer in the bank. Compute the coefcient of variation of C in percent. {Enter your answer in percent, omitting the "9%." symbol. For example, if your answer is "81.9%", you would write 81.9}. Do round
