Problem 1

Use four decimal places in your answers for this problem.

Eighteen (18) people in a department of 162 are fully trained in CPR and AED. A person shows signs of a heart attack. Five (5) people respond. What is the probability that NO (0) person who responded is trained to treat the victim? (Show all of your calculations)

Problem 2

Use three decimal places in your answers for this problem.

An airline company claims their arrivals are on time within an average of +/- 5 minutes and a standard deviation of 2.82 minutes; Normally Distributed. You sample 50 arrivals and find an average of 6.3 minutes late. Can you be at least 90% sure that the airline company's claim is correct? (Show all of your calculations)
