It has been found that 4 percent of the bicycles manufactured at Plant X and 5 percent of the bicycles manufactured at Plant Y are defective. What percent of the bicycles manufactured by the company are not defective?

Suppose that the average waiting time for a patient at a physician’s office is just over29 minutes. To address the issue of long patient wait times, some physicians’ offices areusing wait-tracking systems to notify patients of expected wait times. Patients can adjusttheir arrival times based on this information and spend less time in waiting rooms. Thefollowing data show wait times (in minutes) for a sample of patients at offices that do nothave a wait-tracking system and wait times for a sample of patients at offices with suchsystems.(Please refer to the PatientsWait Data).a. What are the mean and median patient wait times for offices with a wait tracking system?What are the mean and median patient wait times for offices without a wait-tracking system?b. What are the variance and standard deviation of patient wait times for offices with…Urgent Care is organized in to 4 department: Registration (Reg), Waiting (Wait), Treatment (Treat), and Payment & Check Out (PCO).

- section 5.4 Drug usage in the workplace costs employers incredible amounts of money each year. Drug testing potential employees have become so prevalent that drug users are finding it extremely hard to find jobs. Drug tests, however, are not completely reliable. To decrease the likelihood of making an error, all potential employees are screened through two tests, which are independent. One test has a 96% accuracy and the other has a 97% accuracy. Step 1 of 2 : If a person were drug free, what is the probability they would fail both tests? Round your answer to four decimal places, if necessary.A corporation owns several companies. The strategic planner for the corporations believes dollars spend on advertising can to some extend be a predictor of total sales dollars.

- The owner of a small deli is trying to decide whether to discontinue selling magazines. He suspects that only 8.7% of his customers buy a magazine and he thinks that he might be able to use the display space to sell something more profitable. Before making a final decision, he decides that for one day he will keep track of the number of customers that buy a magazine. (b) Assuming his suspicion that 8.7% of his customers buy a magazine is correct, what is the probability that exactly 3 out of the first 14 customers buy a magazine? Give your answer as a decimal number rounded to two digits.4. I was able to convince the plan manager to allow me to make the change to the larger production plant. My job's on the line now!

State your answer as average +/- uncertainty.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.

For your convenience, the table is reproduced below. Table 8a. Consequences of Misconduct: Industry and Firm Discipline No Misconduct Misconduct Remain with the Firm 81.29% 51.99% Leave the Firm 18.71% 48.01% Leave the Industry 8.92% 26.96% Join a Different Firm (within 1 year) 21.05% 9.79% Note: Table 8a displays the average annual job turnover among financial advisers over the period 2005-2015. The table shows, on average, the percentage of advisers that remain with their firm, leave the industry (for at least one year) or join a new firm (within a year). The job transitions are broken down by whether or not the advisor was disciplined for misconduct in the previous year. Consider randomly selecting five financial advisors who were disciplined for misconduct in the previous year. What is the chance that at least one of them leaves the firm?
