Suppose the log-ins to a company's computer network follow a Poisson process with an average of three
counts per minute. What is the mean time between counts? What is the standard deviation of the time
between counts?
O a. NONE
O b. E(X) = 3, SD(X) = 3
O c. E(X) = 0.333, SD(X) = 0.333
O d. E(X) = 0.333, SD(X) = 0.111
