The university policy department must write, on average, five tickets per day to keep department revenues at budgeted levels. Suppose the number of tickets written per day follows a Poisson distribution with mean of 6.5 tickets per day. Interpret the value of the mean.
a) The number of tickets that is written most often is 6.5 tickets per day.
b) half day the days have less than 6.5 tickets written and of the days have more than 6.5 tickets written.
c) If we sampled all day, the arithmetic average number of tickets written would be 6.5 per day.
d) The mean has no interpretation since .5 tickets never be written.
Conduct a two-sample test of means. A study by a bank compared the average savings of customers who were depositors for three years or less with those who had been depositors for more than three years.
