Question: TrafficWeb.org claims that it can deliver 10,000 hits to a Web site in the next 60 days for only $21.95 (www.trafficweb.org, April 26, 2004). If this amount of Web site traffic is experienced, then the time between hits has as a mean of 8.64 minutes (or 0.116 per minute). Assume that your Web site does get 10,000 hits in the next 60 days and that the time between hits has an exponential distribution. What is the probability that the time between two hits is
a. less than 5 minutes?
b. less than 10 minutes?
c. more than 15 minutes?
d. Do you think it is reasonable to assume that the time between hits has an exponential distribution?
