Answer:
The expected number of tickets written would be 6.5 per day.
Step-by-step explanation:
Given that the Sutton police department must write, on average, 6 tickets a day to keep department revenues at budgeted levels.
Suppose the number of tickets written per day follows a Poisson distribution with a mean of 6.5 tickets per day.
This means population parameter i.e. expected value of tickets a day is 6.5
Option I is wrong, because 6.5 is the parameter of Poisson distribution for number of tickets
Option III is wrong because mean is the overall average and hence need not be balanced by exactly half.
Option IV is wrong because mean is the expected value and so we cannot say more than 6.5 tickets
Only correct option is option 2.
The expected number of tickets written would be 6.5 per day.
I believe the answer would be A. C=200x+ 70. Hope this helps!
