The random variable x represents the number of phone calls an author receives in a day, and it has a Poisson distribution with a mean of 8.8 calls. What are the possible values of x?
Is a value of x= 2.2 possible? Is x a discrete random variable or a continuous random variable?
What are the possible values of x?
C
O A. 0, 1, 2, 3, ...
O B. any real number greater than or equal to 0
O C. 1, 2, 3, ...
O D. any real number greater than or equal to 0 and less than or equal to 8.8
Is a value of x = 2.2 possible? Is x a discrete random variable or a continuous random variable?
A value of x = 2.2
possible because x is a
random variable.
