Someone claims that the waiting time, in minutes, between hits at a certain website has the exponential distribution with parameter λ = 0.990. Let X be the waiting time until the next hit. 1. If the claim is true, what is P(X ≥ 5)? (Round the final answer to four decimal places.) 2. Based on the answer to P(X ≥ 5), if the claim is true, is five minutes an unusually long time to wait? (Yes or No) 3. If you waited five minutes until the next hit occurred, would you still believe the claim? Explain. (Yes or No)
