The worst ecological disaster in U.S. history began on April 20, 2010, and was caused by an explosion in the oil rig Deepwater Horizon, which resulted in the deaths of 11 people and triggered a massive oil spill into the Gulf of Mexico. Estimates of the exact amount of the oil spilled vary based on the source, but it is clearly a function of the number of days n it lasted and the leak rate of the oil, estimated by the United States Geological Service (USGS) to be 504,000 gallons each day! The function u that estimates the amount of oil spilled in n days can be defined as u(n) 504,000n gallons/day. To find out how much oil spilled the first month (30 days), let n = 30: u(30) = 504,000(30) - 15,120,000 gallons. According to Bp's worse-case scenario, the amount of oil spilled in n days can be estimated by the function b(n) = 2.520n million gallons, while the function r(n) = 441,000n gallons represents the amount of oil that can be recovered in n days. (a) The function a(n) = b(n) - r(n) represents the actual amount of oil that spilled into the Gulf daily. Find a(n). a(n) = million gallons (b) How many gallons were actually spilled into the Gulf over an 80-day period? million gallons

It is thought that prehistoric Indians did not take their best tools, pottery, and household items when they visited higher elevations for their summer camps. It is hypothesized that archaeological sites tend to lose their cultural identity and specific cultural affiliation as the elevation of the site increases. Let x be the elevation (in thousands of feet) for an archaeological site in the southwestern United States. Let y be the percentage of unidentified artifacts (no specific cultural affiliation) at a given elevation. Suppose that the following data were obtained for a collection of archaeological sites in New Mexico: x 5.00 5.75 6.00 6.50 7.25 y 12 31 41 52 56 Find a for the equation of the least-squares line .

"Radon: The Problem No One Wants to Face" is the title of an article appearing in Consumer Reports. Radon is a gas emitted from the ground that can collect in houses and buildings. At certain levels it can cause lung cancer. Radon concentrations are measured in picocuries per liter (pCi/L). A radon level of 4 pCi/L is considered "acceptable." Radon levels in a house vary from week to week. In one house, a sample of 8 weeks had the following readings for radon level (in pCi/L). 1.9 2.4 5.7 4.3 1.9 8.5 3.9 7.7 (a) Find the mean, median, and mode. mean median mode (b) Find the sample standard deviation, coefficient of variation, and range.

A group of researchers studied the effect of acid rain on wildlife and collected n = 12 samples from streams in different States. They recorded the pH (X) of the water (i.e. units above pH 7), and the BCI, a measure of biological diversity (Y). The data obtained is summarized below.

A student is speeding down Route 11 in his fancy red Porsche when his radar system warns him of an obstacle 400 feet ahead. He immediately applies the brakes, starts to slow down, and spots a skunk in the road directly ahead of him. The "black box" in the Porsche records the car's speed every two seconds, producing the following table. The speed decreases throughout the 10 seconds it takes to stop, although not necessarily at a uniform rate.
Garcia's Garage desires to create some colorful charts and graphs to illustrate how reliably its mechanics "get under the hood and fix the problem." The historic average for the proportion of customers that return for the same repair within the 30-day warranty period is 0.11. Each month, Garcia tracks 130 customers to see whether they return for warranty repairs. The results are plotted as a proportion to report progress toward the goal. If the control limits are to be set at two standard deviations on either side of the goal, determine the control limits for this chart. In March, 8 of the 130 customers in the sample group returned for warranty repairs. Is the repair process in control? TheUCLp equals ? and the LCLp equals ? (Enter your responses rounded to three decimal places.)
