2.) Suppose that the number of requests for assistance received
by a towing service is a Poisson process with rate a = 6 per
hour.
a.) Find the expected value and variance of the number of
requests in 30 minutes. Then compute the probability that there is
at most one request in 30 minute interval.
b.) What is the probability that more than 20 minutes elapse
between two successive requests? Clearly state the random variable
of interest using the context...

Suppose that the number of requests for assistance received by a
towing service is a Poisson process with rate α = 6 per hour.
a) Find expected value and variance of the number of requests in
30-minutes. Then compute the probability that there is at most one
request in 30-minute interval. Clearly state the random variable of
interest using the context of the problem and what probability
distribution it follows.
b) What is the probability that more than 20 minutes...

An administrator wanted to study the utilization of
long-distance telephone service by a department. One variable of
interest (let’s call it X) is the length, in minutes, of
long-distance calls made during one month. There were 38 calls that
resulted in a connection. The length of calls, already ordered from
