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 7.6 calls. what are the possible values of x? is a value of xequals3.2 possible? is x a discrete random variable or a continuous random variable?

Step-by-step explanation:

Given that the random variable x represents the number of phone calls an author receives in a day

Poisson distribution is a discrete distribution with random variable countable.

Here no of calls cannot be in fraction or decimal.

Also given that X is Poisson with mean = 7.6

X is discrete since no of phone calls can take values as 1,2,3

X can take any value from 0 to infinity.

x=3.2 is not possible since 3.2 calls does not exist.

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
