Q8

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.
