The same study also took samples from ocean beaches. Five samples were taken from each of 18 different shorelines worldwide, for a total of 90 samples of size 250 mL. The mean number of plastic microparticles found per 250 mL of sediment was 18.3 with a standard deviation of 8.2. (a) Find a 90% confidence interval for the mean number of polyester microfibers per 250 mL of beach sediment. Round your answers to two decimal places.

Your Turn: The Gas Guzzler Tax is imposed on manufacturers on the sale of new-model cars (not minivans, sport utility vehicles, or pickup trucks) whose fuel economy fails to meet certain statutory regulations, to discourage the production of fuel-inefficient vehicles. The tax is collected by the IRS and paid by the manufacturer. The table (top right) shows the amount of tax that the manufacturer must pay for a vehicle's miles per gallon fuel efficiency. 12.5 13.5 MPG (M) 14.5 15.5 16.5 17.5 18.5 19.5 20.5 21.5 22.5 Tax per Car (T) $6400 $5400 $4500 $3700 $3300 $2600 $2100 $1700 $1300 $1000 $0 1. Plot the data, verify that they are roughly linear, and add a line of best fit. Line of Best Fit: 2. Identify and interpret the meaning of the slope and the vertical intercept. 3.

Case Whole Foods Market Grows Through Mergers and Acquisitions Over three decades ago, four businesspeople who had experience in retailing natural foods through food stores believed that there was a demand for a supermarket for natural foods. As a result, in 1980 in Austin, Texas, they founded the first Whole Foods Market store in a building that had around 10,000 square feet and a staff of 19. This store was quite large compared to health food stores at the time. By 1984, the company was successful enough to expand to Houston and Dallas. In 1988, they purchased the Whole Food Company in New Orleans and expanded there. The next year, they moved into the West Coast with a store in Palo Alto, California. Even though the company has built a number of its own stores, much of the company growth has come through mergers and acquisitions, many of which came in the 1990s in such places as North Carolina, Massachusetts, Rhode Island, both Northern and Southern California, and Michigan. After…
