a. 0.3333

b.0.5000

c. 2

d. 3

Short Answer

Expert verified

The correct answer is Option (a).

Step by step solution

01

Given Information 

The average lifetime of a certain new cell phone is three years. The manufacturer will replace any cell phone failing within two years of the date of purchase. The lifetime of these cell phones is known to follow an exponential distribution.

02

Explanation

μ=3

Therefore, the decay rate will be:

m=1μ

=13

=0.3333

Therefore, option (a) is correct.
