- It is the aim of the Department of Health(DOH) to give measles vaccine to infants. When a barangay health worker in Casili, Mandaue City was asked by the City Health Officer of Mandaue City regarding the proportion of infants who received measles vaccine, the barangay health working claimed that 60% of infants had completed measles vaccine. On the basis of this claim, you as a City health personnel was tasked to verify this claim of the barangay health worker. You were able to interview 120 mothers. Seventy of these mothers confirmed that their children availed of the measles vaccine. You test the claim of the barangay health worker using 0.01 level of significance.Mr. Juan Rafael, the manager of JJ Computer Tech is conducting a study on the number of customers who pay by personal check, by credit card and by debit card.

The number of customers who pay by personal check, by credit card, and by debit card at JJ Computer Tech are the same.B. At least two of the methods of payment in purchasing at JJ Computer Tech are significantly different.C. There is a significant difference in the number of customers who pay by personal check, by credit card, and by debit card at JJ Computer Tech.D. There is no significant difference in the number of customers who pay by personal check, by credit card, and by debit card at JJ Computer TechA cohort study was conducted over five years among 200 trial attorneys and general practice attorneys after stringent tort law reform, to see how many would develop heart conditions over time. In total, 50 attorneys developed heart disease. It was found that 40 who developed disease practiced trial law, while 10 who developed disease did not practice trial law. One hundred (100) who did not develop disease also did not practice trial law, and 50 who did not develop disease practiced trial law. Set up the 2 x 2 table and calculate the appropriate rate of risk
- U.S. Department of Health and Human Services regulations for informed consent state that "an investigator shall seek such consent only under circumstances that provide the prospective subject or the representative sufficient opportunity to consider whether or not to participate and that minimize the possibility of coercion or undue influence." Coercion occurs when an overt or implicit threat of harm is intentionally presented by one person to another in order to obtain compliance. Which of the circumstances could be seen as constituting coercion? Select all that apply. None of the other answer choices are instances of coercion. A researcher has developed a vaccine against a new virus. The researcher is recruiting healthy adult volunteers from an inner city to determine if the vaccine is safe in humans. Volunteers will be paid for their participation.

The accompanying table gives proportions for the various categories of policyholders who have both types of insurance. For example, theproportion of individuals with both low homeowner’s deductible and low auto deductible is .06 (6% of all such individuals).Suppose an individual having both types of policies is randomly selected.a. What is the probability that the individual has a medium auto deductible and a high homeowner’s deductible?b. What is the probability that the individual has a low auto deductible? A low homeowner’s deductible?c. What is the probability that the individual is in the same category for both auto and homeowner’s deductibles?d. Based on your answer in part (c), what is the probability that the two categories are different?e. What is the probability that the…The right to vote (and not to wait) In the past decade, two presidential elections in the United States have witnessedvery long wait times at precincts (voting stations) in states that ultimately decidedthe election (Florida in 2000 and Ohio in 2004).In Philadelphia as well, some voters complained about the long lines in someprecincts, with most complaints coming from precinct A. In 2004, the averagenumber of voters arriving at Precinct A was 35 per hour and the arrivals of voterswas random with inter-arrival times that had a coefficient of variation of 1 (CVa=1).Philadelphia deployed 1 voting machine in Precinct A. Suppose that each voterspent on average 100 seconds in the voting booth (this is the time needed to casther/his vote using a voting machine), with a standard deviation of 120 seconds.
- In a recent submission to a Joint Select Committee of Parliament, the National Consumers' League said “In reality, cow’s milk especially processed cow’s milk, has been linked to a variety of health problems, including: mucous production, haemoglobin loss, childhood diabetes, heart disease, arteriosclerosis, arthritis, kidney stones, mood swings, depression, irritability, allergies.” Researchers know this to be true, though the Committee rejected the submission. Suppose that 34% of the population has mood swings, allergies, irritability and depression (MAID) and is known to consume dairy products. Also, 80% of the populace consumes dairy products. Suppose a randomly chosen dairy products user is tested, what is the probability this person has MAID? Select one: a. 0.425 b. 0.460 c. 0.140 d. 0.272The quality department at an electronics company has noted that, historically, 91% of the units of a specific product pass a test operation, 6% fail the test but are able to be repaired, and 3% fail the test and need to be scrapped. Due to recent process improvements, the quality department would like to test if the rates have changed. A recent sample of 500 parts revealed that 473 parts passed the test, 20 parts failed the test but were repairable, and 7 parts failed the test and were scrapped. (You may find it useful to reference the appropriate table: chi-square table or table)a. Choose the appropriate alternative hypothesis for the test.The rabies vaccine for dogs can save your dog's life. If your dog bites another animal or is on the receiving end of a bite, the vaccine can protect them from a dangerous and potentially fatal illness. Furthermore, in most places, the rabies vaccine for dogs is legally required. The NYC Department of Health wants to know if LESS than 95% of the dogs in the city have been vaccinated with their rabies vaccine. 158,045 of the 165,000 dogs examined had their rabies shots. Risk no more than 5% Type I error. Do you retain or reject the null hypothesis? Retain the null. Reject the null.
