A manufacturing company changes an acceptance scheme on items from a productionline before they are shipped. An inspector takes 1 item at random from a box of 21items, inspects it, and then replaces it in the box; a second inspector doeslikewise. Finally, a third inspector goes through the same procedure. If any of the threeinspectors find a defective, the entire box is sent back for 100% screening. If nodefectives are found, the box is shipped.(a) What is the probability that a box containing 2 defectives will be shipped?(b) What is the probability that a box containing only 1 defective will be sent backfor screening?(a) The probability that a box containing 2 defectives will be shipped is .7406.(Round to four decimal places as needed.)(b) The probability that a box containing only 1 defective will be sent back for screeningis(Round to four decimal places as needed.) A manufacturing company uses an acceptance scheme on items from a production linebefore they are shipped. The plan is a two-stage one. Boxes of 24 items are readiedfor shipment, and a sample of 5 items is tested for defectives. If any defectivesare found, the entire box is sent back for 100% screening. If no defectives are found, thebox is shipped.(a) What is the probability that a box containing 3 defectives will be shipped?(b) What is the probability that a box containing only 1 defective will be sent backfor screening?(a) The probability that a box containing 3 defectives will be shipped is(Round to four decimal places as needed.)

Statewide, the police clear by arrest 35% of the robberies and 42% of the aggravated assaults reported to them. A researcher takes a random sam- ple of all the robberies (N 5 207) and aggravated assaults (N 5 178) reported to a metropolitan police department in one year and finds that 83 of the rob- beries and 80 of the assaults were cleared by arrest. Are the local arrest rates significantly different from the statewide rates? Write a sentence or two inter- preting your decision.
A county clerk wants to improve voter registration. He wants to send out reminders in the mail to all citizens in the county who are eligible to vote. To determine if it will actually improve voter registration, a random sample of 1250 potential voters was taken. No reminders were sent out to a group of 625 eligible voters and of those 625, 299 registered to vote. Reminders were sent out to another group of 625 voters and of those 348 registered to vote. The county clerk claims that the proportion of people who registered was significantly greater in the group that was sent the reminders. Using a 0.10 significance level, test the claim that the proportion of registered voters is higher in the group that received the reminders. What is the test statistic for this test?

It’s that time of year again at Isaac’s Fireworks Store! New Year’s! Sale! Sale! Sale! However, Isaac is less than excited because last year he had a lot of complaints about a large number of defective fireworks that he sold. Isaac wants to know what percentage of his firework stock is defective. First, he plans to test his bottle rockets, so he takes a sample of 200 randomly chosen bottle rockets and he tests them. Of the 200, 14 failed. Construct a 80% confidence interval for the true proportion of bottle rockets that will fail.
Does advertising influence children as young as three? Researchers at Stanford University conducted a taste test with preschoolers. Each preschooler tasted two identical samples of five food items (hamburger, french fries, chicken nuggets, baby carrots, and apple slices). For each item, the children tasted one sample wrapped in a McDonald's wrapper and the other sample in an identical, but unbranded, wrapper. Some children tasted the sample in the branded wrapper first, others tasted the sample in the unbranded wrapper first. Consistently for all food items, the majority of preschoolers preferred the food in the McDonald's wrapper over the one in the unbranded wrapper, even though both samples were identical. [Source: Robinson, T. N., et al. "Effects of fast food branding on young children's taste preferences." Archives of Pediatrics & Adolescent Medicine 161 C2007): 792–797]. The researchers found that the preschoolers who watched more television or ate more often at McDonald's were…

Diana Baniak, searching for an Ecology class, knows that it must be in one of eight classrooms. Since the professor does not allow people to enter after the class hasbegun, and there is very little time left, she decides to try just five of the rooms at random. How many of the possible different selections of five rooms will succeed in locating the class? There are ________________ successful selections. Note that the successful selections will be those that have, as one of the selections, the correct classroom. Thus, compute the number of ways to choose the incorrect classrooms.
g) The Lady Tasting Tea Experiment. An English lady, Muriel Bristol, claimed that she can tell whether tea or milk was added first to a cup. So as a researcher, you want to test whether she can really tell whether tea or milk was added first. But how would you do it? A possible research design: Give her eight cups, four where tea is added first and the other four where milk is added first, in random order. Then ask her to pick out the four cups where the milk is added first. After you conducted the experiment and collected the data, how do you decide whether she can truly tell the difference or she was just guessing. Our intuition tells us that the more cups she gets correctly, the more likely that she is NOT guessing. "If the Lady is just guessing, the probability of getting it all correctly is 1.4%." Now using your knowledge on combinatorics and probability, explain how this number was calculated? h) Suppose you flip four fair coins. What is the probability that you will get all…
