Freshwater fish (from fish farms) has been touted as a good replacement for sea fish as pollutants from factories and sewage plants have deposited chemicals that have severely contaminated sea fish. Now fish from some seas are not safe to eat. Nevertheless, it is discovered that farm fish are not so healthy after all and have high mortality rates. Therefore, the farmers use antibiotics to keep them alive. These antibiotics can have dangerous consequences on unsuspecting humans. Suppose that if farm fish is randomly and regularly tested and it is found that 25% is okay for consumption, 35% have dangerous traces of antibiotics and 40% have deadly untreated diseases. What is the probability of a random sample of 10 such fish was found to have 3 okay, 3 with antibiotics and 4 with the deadly untreated disease?

Researchers are interested in testing the effectiveness of a new immunosuppressive therapy to be used post-transplant to reduce graft failure in the host. Suppose researchers investigating this new therapy are concerned about the dangerous side-effects of the drug. For instance, participants that would like to enroll in the study are not allowed to already have diabetes, as the immunosuppressive agent has been found to drastically increase fasting glucose levels, which could be very dangerous for diabetics. This means, however, that participants that enter and are treated with the new drug may develop diabetes as time goes on. Suppose the following table addresses the incidence of diabetes in the study depending on treatment group. (α=.01) Type II Diabetes No Type II Diabetes Total Investigational Drug 45 32 77 Best standard of Care 35 50 85 Total 80 82 162 Based on this information complete the hypothesis steps for Chi-Squared below:…
It has been observed that some persons who suffer colitis, again suffer colitis within one year of the first episode. This is due, in part, to damage from the first episode. The performance of a new drug designed to prevent a second episode is to be tested for its effectiveness in preventing a second episode. In order to do this two groups of people suffering a first episode are selected. There are 55 people in the first group and this group will be administered the new drug. There are 45 people in the second group and this group will be administered a placebo. After one year, 11% of the first group has a second episode and 9% of the second group has a second episode. Conduct a hypothesis test to determine, at the significance level 0.1, whether there is reason to believe that the true percentage of those in the first group who suffer a second episode is different from the true percentage of those in the second group who suffer a second episode? Select the [Alternative Hypothesis,…
Par, Inc.Par, Inc. is a leading manufacturer of golf equipment. Par's manager believes that the company's market share will increase with the introduction of a highly durable, cut-resistant golf ball. To this end, Par's research group has been testing a new coating for the balls, designed to give resistance to cuts and provide a product with greater durability. Testing done with the coating has been promising.One of the researchers expressed concern about the effect of the new coating on the ball's travel distance. Par wants the new cut-resistant model to offer a travel distance comparable to today's golf balls. To compare the travel distance of the two types of balls, 40 of each model were subjected to distance tests, which were carried out with a ball-throwing machine in order that the difference between the average flight distances between the two models could be attributed to its different peculiarities. The results of the tests, with the distances expressed to the nearest yard,…
The 2019-2020 flu season was especially tough.By the end of the season, an estimated total of 49 million people in the United States had contracted the flu, of whom an estimated 79,000 died from the flu. Assume that the US population was 300,000,000 during the 2019-2020 flu season and that during the season, a total of 2.9 million Americans died from all causes (including the flu). Assume the population of the US remained the same at the midpoint of the season. Report mortality rates per 100,000. Be sure to express the measure in the correct format. c.What was the flu-related mortality rate during the 2019-2020 flu season? d.What is the all-cause mortality rate during the 2019-2020 flu season? e.In a country with an age distribution that is much younger than in the US, the proportionate mortality rate from flu in 2019 was 5%. Based on this information alone, can we determine that the risk of dying from flu in 2019 was higher in this country compared to the US? Why or why not?
You are tasked to design a prevention program to target one of two different infectious diseases. You only have funding to target one of them, so you must choose wisely. The first infectious disease (Disease A) has a case fatality rate of close to 75%, but a very low cause-specific mortality rate. The other (Disease B) has a case fatality rate less than 0.1%, but a relatively high cause-specific mortality rate. Which do you choose? Why
You are on placement in a GP practice which holds a nurse-led asthma clinic once a week. The nurse practitioner in charge of the clinic tells you that asthma affects around 11% of the Australian population, and results in around 40,000 hospital admissions each year. She also tells you that the common pharmacological treatments can have long-term side effects, so she is keen to promote holistic methods to assist patients in controlling their asthma. You are interested to know whether diet can have an effect on asthma, and decide to find out. Construct a searchable clinical question using the PICO formula, identifying the PICO elements clearly.
In laboratories where clinical tests are carried out, two types of test are available for the detection of a highly contagious virus. The Type A test is very fast and inexpensive while the Type B test is a test that requires more time to obtain a diagnosis and is more expensive. It is known that the economic test. Type A, generates correct diagnosis (C) in 60% of cases. While the Type B test provides the correct diagnosis (C) in 99% of cases. If after six months of quarantine due to this virus the health secretary realizes that 80% of the tests carried out in the state correspond to Type A economic tests and only 20% were Type B. If it is known that a test made an incorrect diagnosis. What is the probability that the Type A economic test did? .9937 .24844 .322 .6211 .3788
Thomas and Camille are international visiting scientists with research interests in horticultural and environmental issues in urban areas. They participate in various studies performed by Ville de Montréal. More specifically, they address issues related to plant diseases in city gardens, air and water quality, and food waste management. The viruses causing problems in strawberry plants are mainly spread by one insect, the strawberry aphid. Camille believes that as aphids feed on leaves, they transmit viruses that can cause a rapid decrease in plant growth. She decides to verify whether or not the number of strawberry aphids found on a plant could be linked to its growth. She therefore randomly chooses 5 strawberry plants at the same stage of development in a virus-infested garden. For each individual plant, she first collects all the aphids present on the plant and weighs them, and then weighs the entire plant to have a measure of plant growth. She obtains the following data.…
Imagine you need to come up with a diagnostic test to monitor the viral load of patients with HIV. If the viral load is higher than a set standard, there is evidence the anti-retroviral therapy is no longer working and the patient needs to be moved to a different therapy that costs more money. Thus, false positives incur higher costs. However, if the test misses higher than normal viral loads (for patients in treatment), then the patient runs the risk of developing AIDS. Hence, false negatives result in a likely deadly disease. How would you balance these two types of error in devising your test? Minimize beta by raising the one-tailed alpha, since greater power will reduce false negatives and save patients O Minimize the one-tailed alpha, since lower P-values indicate the test is highly significant and prevent prematurely switching the patients Minimize the one-tailed alpha and beta, since this action will prevent prematurely switching the patients and reduce false negatives, thereby…
Beryllium is an extremely lightweight metal that is used in many industries, such as aerospace and electronics. Long-term exposure to beryllium can cause people to become sensitized. Once an individual is sensitized, continued exposure can result in chronic beryllium disease, which involves scarring of the lungs. In a study of the effects of exposure to beryllium, workers were categorized by their duration of exposure (in years) and by their disease status (diseased, sensitized, or normal). The results were as follows: Duration of Exposure <1 1 to <5 ≥5 Diseased 14 13 18 Sensitized 11 20 15 Normal 78 140 209 Test the hypothesis of independence. Use the a=0.10 level of significance and the P-value method with the TI-84 Plus calculator. What do you conclude? State the null and alternate hypotheses.
