Some Internet companies sell a service that will boost a website's traffic by delivering additional unique visitors. Assume that one such company claims it can deliver 1,000 visitors a day. If this amount of website traffic is experienced, then the time between visitors has a mean of 1.44 minutes (or 0.6944 per minute). Assume that your website gets 1,000 visitors a day and that the time between visitors has an exponential distribution. What is the probability that the time between two visitors is

1. Less than 1 minute?

2. Less than 2 minutes?

3. More than 3 minutes?

4. Do you think it is reasonable to assume that the time between visitors has an exponential distribution? Explain
