Suppose that there are two supervisors at Kardashian restaurant (Kim and Kylie), and the # of customer complaints differs based on the supervisor on duty. This is determined according to a Poisson process. The quality of service of one day does NOT affect the quality of service on the next day.

Supervisor on duty:	Average # of customer complaints (per day):	Days on duty (out of 5 days):
Kim	2 per day	2 out of 5 days
Kylie	3 per day	3 out of 5 days

Answer the following questions based on the information given above:

i) Assuming that Kylie is on duty, solve for the expected # of customer complaints in the next 2 days.

ii) Assuming that Kylie is on duty, solve for the probability that there will be no customer complaints tomorrow.

iii) If there was AT LEAST 1 customer complaint yesterday, what's the probability that Kim was on duty?

iv) Solve for the probability that there will be no customer complaints in the next 2 days.

Suppose you want to eat lunch at a popular restaurant. The restaurant does not take reservations, so there is usually a waiting time before you can be seated. Let x represent the length of time waiting to be seated. From past experience, you know that the mean waiting time is μ = 17.2 minutes with σ = 3.8 minutes. You assume that the x distribution is approximately normal. (Round your answers to four decimal places.)(a) What is the probability that...
