adapted from Safe and Healthy Travel to a Mass GatheringCenters for Disease Control and Prevention      International events draw huge crowds and come with unique risks to travelers. Whether they are planned years in advance, such as the Olympics, or happen more spontaneously, such as a president's memorial service, mass gatherings present several problems. They are associated with crowding at venues, poor hygiene from temporary food and sanitation facilities, and challenging security situations. The risk of infectious diseases increases because of crowded conditions and the influx of attendees from around the world.     A mass gathering can be thought of as any gathering of people that is large enough to strain local resources. Typically, they involve a large number of people—sometimes numbering in the millions—at a specific location, for a specific purpose, and for a defined time frame. 16   Select the correct location on the image.

Democratic and Republican presidential state primary elections differ in the way winning candidates are awarded delegates. In Republican states, the winner is awarded all the state's delegates; conversely, the Democratic state winner is awarded delegates in proportion to the percentage of votes. This difference led to an article on making your vote count. Consider scenario where you are one of five county commissioners voting on an issue, where each commissioner is equally likely to vote for or against. Complete parts and b below. a. Your vote (the decisive vote) counts only if the other four voters split, 2 in favor and 2 against. Use the binomial distribution to find the probability that your vote counts. The probability that your vote counts is 0.375. (Type an integer or a decimal. Do not round.) b. If you convince two other commissioners to "vote in bloc" (all agree to vote among yourselves first, and whatever the majority decides is the way all three will vote, guaranteeing that…

Overbooking is the practice of selling more items than are currently available. Overbooking is common in the travel industry; it allows a vehicle (airline, train, bus, cruise ship, hotel, and so forth) to operate at or near capacity, despite cancellations, no-shows, or late arrivals. Overselling is when more confirmed customers show up to use the vehicle than there is space available. When this happens, at least one customer will be denied the service that they paid for, either voluntarily (sometimes with an incentive provided by the supplier) or involuntarily. This is called getting "bumped." Suppose that for a particular flight, an airline believes that 2% of ticket holders do not make the flight. The jet making the trip holds 189 passengers. If the airline sells 192 tickets, what is the probability that the flight will be oversold and they will have to bump a passenger? Assume that cancellations are independent. Calculate the probabilities that one, two, and three people will be…

3. Scenario It is believed that large doses of acetaminophen (the active ingredient in over the counter pain relievers like Tylenol) may cause damage to the liver in nearly half of those tested. A researcher wants to conduct a study to estimate if the proportion of acetaminophen users who have liver damage is the same as previously reported. For participating in this study, he will pay each subject $20 and provide a free medical consultation if the patient has liver damage. Part A If he wants to limit the margin of error of his 98% confidence interval to 2%, what is the minimum number of subjects he needs?  (answer should be in the form of x,xxx) the minimum amount of money he needs to set aside to pay his subjects? $  (answer should be in the form of $xx,xxx) Part B The amount you calculated in Part A is substantially over his budget so he decides to use fewer subjects. Will this change increase or decrease the width of his confidence interval?  Will this new confidence interval be…
