Chapter 5: Q. 49 (page 350)

Use the following information to answer the next ten exercises. A customer service representative must spend different amounts of time with each customer to resolve various concerns. The amount of time spent with each customer can be modeled by the following distribution: X~Exp(0.2)

What is the mean?

Short Answer

Expert verified

Mean is 5.

Step by step solution

01

Concept

As per provided information, X~Exp(0.2).

As per Equation of Exponential Distribution, role="math" localid="1648187330135" X~Exp(m).

Mean can be described as the reciprocal of decay variablem.

02

Finding the mean 

As per Step 1,

m=0.2

It is known that, Mean is the reciprocal of the decay variable m

role="math" localid="1648187916729" 渭=1m=10.2=5

Therefore, the mean is 5.
