KOne hundred volunteers were divided into two equal-sized groups. Each volunteer took a math test that involvedtransforming strings of eight digits into a new string that fit a set of given rules, as well as a third, hidden rule. Prior totaking the test, one group received 8 hours of sleep, while the other group stayed awake all night. The scientistsmonitored the volunteers to determine whether and when they figured out the rule. Of the volunteers who slept, 39discovered the rule; of the volunteers who stayed awake, 16 discovered the rule. What can you infer about theproportions of volunteers in the two groups who discover the rule? Support your answer with a 95% confidenceinterval.DEFENDLet p₁ be the proportion of volunteers who figured out the third rule in the group that slept and let på be the proportionof volunteers who figured out the third rule in the group that stayed awake all night.The 95% confidence interval for (P₁-P₂) is ().(Round to the nearest thousandth as needed.)

On a particularly boring transatlantic flight, one of the authors amused himself by counting the heads of the people in the seats in front of him. He noticed that all 28 of them either had black hair or had a whole row to themselves (or both). Of this total, 25 had black hair and 5 were fortunate enough to have a whole row of seats to themselves. How many of the black- haired people had whole rows to themselves? people
Mr. Smith decides to organize a potluck party with neighbors on a weekend. John Smith and his wife Mary Smith and his daughter Judy Smith will prepare three different salad dishes. John's right side neighbor Jenny Jones and Bob Jones will prepare two desserts. John's left side neighbor Linda will prepare one meat dish. John's cross street neighbor Sue will prepare soup. John wants to figure out how many different ways for him to taste all dishes in order (assuming he will taste all salads, meat, desserts and soup). (Note : For example, "Salad, Soup, Salad, Meat, Dessert, Salad, Dessert" is one of the possible order he can try.

Suppose I gave you a bag of M&M’s, but I didn’t let you see the original packaging so you can’t determine which plant made the M& M’s. Your job is to count the number of candies of each color in your bag and figure out which plant made your bag. What test should you do to determine this?
A shoe company wants to test an updated model of a running shoe on its wear after one month of running. Which of the following describes a matched pairs design? They recruit 50 people who run on a regular basis to participate in their study. They will have the runners wear the shoes when they run for two months. After two O The subjects are numbered 1-50, and these numbers are put into a random number generator. The first 25 random numbers, ignoring repeats, represent the subjects assigned to the new model group. The remaining 25 subjects will wear the original model. months, the wear on the shoes will be determined using the depth of the tread and flexibility of the toe box. The wear between the new model and the original model will then be compared. The subjects' names are written on equal-sized slips of paper and placed into a hat. A researcher then reaches in and pulls out 25 slips of paper. These subjects are assigned to the new model group. The remaining 25 subjects will be…
The Norfolk Times recently sponsored a "Sail Around the World" race that pitted dozens of sailors against each other to see who could circumnavigate the globe, solo, in the fewest number of days. The first racer finished in 270 days, and another finished every 4 days after that until day 286. Using only the clues below, match each sailor who actually finished the race to his or her boat type (one of which was a sloop), and determine how many days it took them to complete their circumnavigation. A. Debra Decker took 4 fewer days to finish than the competitor in the schooner. B. Wendell Orr didn't finish in exactly 282 days. C. Neal Bundt was either the competitor who finished in 270 days or the competitor in the catamaran. D. Of Neal Bundt and Ed Alexander, one finished in 286 days and the other used the ketch. E. The person who finished in 270 days used the gaff cutter. F. Neal Bundt took 12 more days to finish than Gil Baxter.
