The waiting times on hold for a call to a customer service department are observed to have the following probability distributio

Elina [12.6K]

Answer:

b. 9.2 minutes

Step-by-step explanation:

To find the expected waiting time for a random call from the sampie given by using the formula:

$\sum (f(X)) = \dfrac{\sum f (x) \times x}{\sum x}$

number of calls (x) waiting time f(x) in minutes f(x) *(x)

0 0 0

2 3 6

4 10 40

6 15 90

8 10 80

10 6 60

$\sum x = 30$ $\sum f(x) *x = 276$

Therefore:

$\sum (f(X)) = \dfrac{276}{30}$

$\sum (f(X)) = 9.2$
