Lie detectors have a 15% chance of concluding that a person is lying even when they are telling the truth. A bank conducts interviews of job applicants with the use of the lie detector. There are 15 applicants who are interviewed.

a) Assuming all 15 applicants tell the truth, what is the probability that the lie detector will conclude that all 15 are telling the truth?

b) Assuming all 15 applicants tell the truth, what is the probability that the lie detector will conclude that at least one is lying?

c) What are the mean and standard deviation of the 15 truthful applicants?

d) What is the probability that the number of truthful applicants classified as liars is greater than the mean?

DHL Shipping claims that it ships 95% of its orders within three working days. You select a simple random sample of 100 orders and discover that only 91 of them shipped on time.

a) If DHL really does ship 95% on time, what is the probability that the company shipped 91 or fewer out of 100 orders were shipped on time?
b) A marketer from UPS jumps on the research stating, “They claim 95% on time, but by their own research they only ship 91% on time!” Provide a rebuttal to the UPS marketer in non-statistical terms
