Suppose that the log-ons to a computer network follow a poisson process with an average of 2 counts per minute. (a) what is the mean time between counts (in minutes)? (round yours answers to 3 decimal places.) (b) what is the standard deviation between counts (in minutes)? (round yours answers to 3 decimal places.) (c) let x denote the time between two counts. if it is an average of 3 counts per minute, find the value of x such that p(x
