Answer: The mean number of checks written per day
Standard deviation
Variance
Step-by-step explanation:
Given : The total number of checks wrote by person in a year = 126
Assume that the year is not a leap year.
Then 1 year = 365 days
Let the random variable x represent the number of checks he wrote in one day.
Then , the mean number of checks wrote by person each days id=s given by :-
Since , the distribution is Poisson distribution , then the variance must equal to the mean value i.e.
Standard deviation :
Answer:
(-4, -3) y (3, -5)
{-12 y, 15 y}
-12 y + 15 y = 3 y
(3 y)/2
3 sqrt(41) abs(y)
