Transcribed Image Text: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 7.8 calls. What are the possible values of x? Is a value
of x= 3.6 possible? Is x a discrete random variable or a continuous random variable?
What are the possible values of x?
O A. any real number greater than or equal to 0 and less than or equal to 7.8
O B. any real number greater than or equal to 0
O C. 0, 1, 2, 3, ..
O D. 1, 2, 3, ..
Is a value of x=3.6 possible? Is x a discrete random variable or a continuous random variable?
Avalue of x= 3.6
possible because x is a
random varlable.
