Question 1

The time between arrivals at an ATM machine follows an exponential distribution with θ = 10 minutes. Find the mean and standard deviation of this distribution.
◦ Mean = 3.16, Standard Deviation = 3.16
◦ Mean = 10, Standard Deviation = 10
◦ Mean = 10, Standard Deviation = 3.16
◦ Mean = 10, Standard Deviation = 100

Question 2

Suppose that the random variable x has an exponential distribution with θ = 3.

a. Find the probability that x assumes a value more than three standard deviations from μ.
b. Find the probability that x assumes a value less than one standard deviation from μ.
c. Find the probability that x assumes a value within a half standard deviation of μ.
