Question 1

The mean clotting time of blood is 7.35 seconds, with a standard deviation of 0.35 seconds. What is the probability that blood clotting time will be less than 7 seconds? Assume the distribution is normal.
◦ 0.16
◦ 0.14
◦ 0.15
◦ 0.84

Question 2

The time between major earthquakes in a particular region of the Mediterranean is a random variable with probability density function f(x) = e-x/1600 for x in [0, ∞), where x is measured in days. Find the expected value and the standard deviation of this probability density function.
◦ μ = 1600 days; σ = 3200 days
◦ μ = 3200 days; σ = 2262.4 days
◦ μ = 1600 days; σ = 2262.4 days
◦ μ = 1600 days; σ = 1600 days

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
