In a CSV file there is data that shows only months and number of traffic accidents in each month.
In an assignment about Poisson distribution and traffic accidents, they ask:
What is the expected number of accidents per month if they are distributed with a Poisson distribution parameter μ?
They also ask: according to the data in CSV file, the average traffic accident per month is 7. How can we use this to estimate the μ?
After reading about Poisson distributions online I'm confused:
Isn't the parameter μ the same as expected number of accidents per X time?
In this case isn't μ = 7 when average traffic accident per month is also 7?
