Tasks are sent to a supercomputer at an average rate of 6 tasks per minute. Their arrivals are modeled by a Binomial counting process with 2-second frames.
(a) Compute the probability of more than 2 tasks sent during 10 seconds
(b) Compute the probability of more than 20 tasks sent during 100 seconds. You may use a suitable approximation

In drawing an inference using a single mean in hypothesis testing, you often have a choice between doing a z-test or a t-test. Many researchers will always choose to do the t-test even under circumstances where the z-test would work as well.
