The university police department keeps track of the number of tickets it write in a year. last year the campus police wrote 1460 tickets. ticket writing on campus follows a poisson process. what is the standard deviation of the number of tickets written per day by the campus police?

2

Step-by-step explanation:

We are given that Ticket writing on campus follows a Poisson process.

Last year the campus police wrote 1460 tickets

So,

1 year = 365 days

So, E(Y) =

So,  the standard deviation of the number of tickets written per day by the campus police =

Hence the standard deviation of the number of tickets written per day by the campus police is 2

if x = 1, then the answer is 3.5
