Question

The time that customers wait to be served at the delicatessen for a grocery store follows the uniform distribution between 0 and 7 minutes. What is the mean of this distribution?

Answer 1

Answer:

3.5

Step-by-step explanation:

Let X be our random variable  in the interval [0,7]

We notice that this is a continuous random variable of uniform distribution.

The mean of expected value of a uniform random variable X is:

$E(X)=\frac{(a+b)}{2}\\\\=\frac{(7+0)}{2}\\\\\\=3.5$

Hence, the mean of the distribution is 3.5
