The question as text

A certain website receives an average of n hits per hour. In the past the value of n was 14.4. After making some improvements, the owner of the website wishes to test whether the value of n has increased. He chooses a 10-minute period at random and finds that there were 6 hits during this period. You may assume that the number of hits the website receives in any given time period follows a Poisson distribution.
