Let C represent the event that a person has cancer. Let D represent the event that a person is diagnosed with cancer. In a certain region of the country it is known from past experience that the probability of selecting an adult over 40 years of age with cancer is 0.08. The probability of a doctor correctly diagnosing a person with cancer as having the disease is P(D | C) = 0.84, and the probability of incorrectly diagnosing a person without cancer as having the disease is P(D | C 0 ) = 0.04. What is the probability that a person diagnosed as having cancer actually has the disease, i.e. find P(C | D)? Round all values to 4 decimals, if needed.

A world record was set for the men’s 100-m dash in the 2008 Olympic Games in Beijing by Usain Bolt of Jamaica. Bolt "coasted" across the finish line with a time of 9.69 s. If we assume that Bolt accelerated for 3.00 s to reach his maximum speed, and maintained that speed for the rest of the race, calculate his maximum speed and his acceleration. (b) During the same Olympics, Bolt also set the world record in the 200-m dash with a time of 19.30 s. Using the same assumptions as for the 100-m dash, what was his maximum speed for this race?

What is the probability that exactly two of the selected bulbs are rated 75-W? b. What is the probability that all three of the selected bulbs have the same rating? c. What is the probability that one bulb of each type is selected? d. Suppose now that bulbs are to be selected one by one until a 75-W bulb is found. What is the probability that it is necessary to examine at least six bulbs?

AARP reported on a study conducted to learn how long it takes individuals to prepare their federal income tax return (AARP Bulletin, April 2008). The data contained in the Microsoft Excel Online file below are consistent with the study results. These data provide the time in hours required for a sample of 40 individuals to complete their federal income tax returns. Assume that the population standard deviation is known to be σ = 9 hours. Open spreadsheet What is the 95% confidence interval estimate of the mean time it takes an individual to complete a federal income tax return (1 decimal)?
