- Cigarettes 2009. In 1999, the Centers for Disease Controland Prevention estimated that about 34.8% of high schoolstudents smoked cigarettes. They established a nationalhealth goal of reducing that figure to 16% by the year2010. To that end, they would be on track if they achieveda reduction to 17.7% by 2009. In 2009, they released aresearch study in which 19.5% of a random sample of5080 high school students said they were current smokers.Is this evidence that progress toward the goal is off track?a) Write appropriate hypotheses.b) Verify that the appropriate assumptions are satisfied.c) Find the P-value of this test.d) Explain what the P-value means in this context.e) State an appropriate conclusion.f) Of course, your conclusion may be incorrect. If so,which kind of error did you commit?The Vintage Restaurant, on Captiva Island near Fort Myers, Florida, is owned and operated by Karen Payne. The restaurant just completed its third year of operation. Since opening her restaurant, Karen has sought to establish a reputation for the Vintage as a high-quality dining establishment that specializes in fresh seafood. Through the efforts of Karen and her staff, her restaurant has become one of the best and fastest growing restaurants on the island. To better plan for future growth of the restaurant, Karen needs to develop a system that will enable her to forecast food and beverage sales by month for up to one year in advance. Table 17.25 shows the value of food and beverage sales ($1000s) for the first three years of operation. Dependent variable: What is the variable: ___________________________________________ How it is measured, i.e. what units or categories are used (e.g., revenue measured in “dollars”; height measured as “short, average, tall”)…2.

- Can you guys help me on this? Thank you!Entomologists estimate that an average person consumes almost a pound of bug parts each year. There are that many insect eggs, larvae, and miscellaneous body pieces in the foods we eat and the liquids we drink. The Food and drug administration (FDA) sets a food defect action Level (FDAL) for each product: Bug-part concentrations below the FDAL are considered acceptable. The legal limit for peanut butter, for example, is thirty insect fragments per hundred games. Suppose the crackers you just bought from a vending machine are spread with twenty grams of peanut butter. What are the chances that your snack will include at least five crunchy critters?calculator Google Search × New Tab Quiz: Practice Questions for Am × + tcinstructure.com/courses/2438849/quizzes/8459601/take D Question 1 uncements 123 les 3365 omes & Events ent Resources 1 pts Assuming there were no buying/selling fees, what would be the total capital gain if 107 shares of DCBA stock were purchased for $33.88 per share and all 107 shares were sold for $41.66 per share six months later?

- _) Jane bakes sourdough loaves, which are full of gluten. Unfortunately, John is allergic to gluten and wants to bake gluten-free loaves. John does not have their own “starter” (a mix of yeast, flour, and water that makes a loaf rise in the oven). Jane's starter is 50g of water and 50g of flour with gluten, and a microscopic amount of yeast that we will ignore. Jane gives John 50g of her starter. For John's first loaf, they replace the missing half of their starter with 25 g of gluten-free flour and 25g of water. This means their starter is now 25g of gluten-free flour, 25g of flour with gluten, and 50g of water. Once the yeast in this starter is fully activated, John is ready to make their first loaf. To bake the loaf they mix 50 g (half) of the starter with 225g of gluten-free flour and 225g of water, meaning the loaf is alwaysThe Ancient Murrelet is a plucky little bird of the auk family that lives in colonies on islands off the northern Pacific coasts of Russia, Alaska and Canada. Half of the world population breeds on the islands of Haida Gwaii, British Columbia. Since these birds lay their eggs in burrows on the forest floor, the nestlings are highly susceptible to predation. Their populations have been greatly reduced over the past century by mammalian predators (deer, raccoons, rats) introduced to their breeding islands after contact was established between the Haida people and outsiders. Conservation efforts have only recently been undertaken. A multi-year population study on one island, now closed to human visitors, has produced the following function that describes the observable decline: P(t) = 5-√√2t+4 where P(t) is the island population in thousands and t is the time in years since January 1, 2008, when the study was started. The goal is to graph and interpret this function in this problem…A hospital dietitian prepares breakfast menus every morning for the hospital patients. Part of the dietitian’s responsibility is to make sure that minimum daily requirements for vitamins A and B are met. At the same time, the cost of the menus must be kept as low as possible. The main breakfast staples providing vitamins A and B are eggs, bacon, and cereal. The vitamin requirements and vitamin contributions for each staple follow: Vitamin mg/Egg mg/bacon strip mg/Cereal Cup Min. Daily Requirement A 2 4 1 16 B 3 2 1 12 An egg costs $0.04, a bacon strip costs $0.03, and a cup of cereal costs $0.02. The dietitian wants to know how much of each staple to serve per order to meet the minimum daily vitamin requirements while minimizing total cost. 1.
