(1) The Food and Drug Administration (FDA) states that the Wellcome Elisa test for HIV (human immunodeficiency virus, which causes AIDS) is positive 99.3 percent of the time among those persons who carry the HIV virus (called the sensitivity of the test). Furthermore, FDA has concluded that the test is negative 99.99 percent of the time on those persons who do not have the HIV virus (called the specificity of the test). State these results as conditional probabilities. Let T+ stand for the event that the test is positive and let T- stand for the event that the test is negative. Similarly, Let HIV+ stand for the event that the person carries the HIV virus and HIV- stand for the event that the person does not carry the HIV virus. With this notation, the following answers are proposed. (a) P(T + |HIV+) = 0.993, (b) P(T + |HIV-) = 0.993, (c) P(T – |HIV+) = 0.993, (d) P(T + |HIV+) = 0.993, (e) P(T +|HIV+) = 0.993, Р(Т — |НIV-) 3D 0.9999. Р(Т — |НIV-) — 0.9999. P(T – |HIV-) = 0.9999. Р(T + |HIV-) 3 0.9999. Р(Т — |НIV+) — 0.9999. The correct answer is (a) (b) (c) (d) (e) N/A (Select One)

The National Institute of Mental Health published an article stating that in any two-year period, approximately 10.5percent of American adults suffer from depression or a depressive illness. Suppose that in a survey of 150 people in a certain town, eight of them suffered from depression or a depressive illness. If you were conducting a hypothesis test to determine if the true proportion of people in that town suffering from depression or a depressive illness is lower than the percent in the general adult American population, what would the null and alternative hypotheses be?
In a study of whether taking a garlic supplement reduces the risk of getting a cold, participants were assigned to either a garlic supplement group or to a group that did not take a garlic supplement.† Based on the study, it was concluded that the proportion of people taking a garlic supplement who get a cold is lower than the proportion of those not taking a garlic supplement who get a cold. Do you think that the study was conducted in a reasonable way? What additional information would you want in order to evaluate this study? (Select all that apply.) A) whether the patients knew which treatment they were receiving B) whether the patients were randomly assigned to the treatments C) whether the patient's last name started with A through M D) whether the patient's cold lasted more than a week E) whether the experiment was conducted on a sufficient number of patients so that the differences observed could not be attributed to chance
A manufacturer of hand-held calculators receives large shipments of printed circuits from a supplier. It is too costly and time-consuming to inspect all incoming circuits, so when each shipment arrives, a sample is selected for inspection. Information from the sample is then used to test H0: p = 0.01 versus Ha: p > 0.01, where p is the actual proportion of defective circuits in the shipment. If the null hypothesis is not rejected, the shipment is accepted, and the circuits are used in the production of calculators. If the null hypothesis is rejected, the entire shipment is returned to the supplier because of inferior quality. (A shipment is defined to be of inferior quality if it contains more than 1% defective circuits.) In this context, define Type I and Type II errors. (Select all that apply.) a. A Type I error is obtaining convincing evidence that more than 1% of a shipment is defective when in fact (at most) 1% of the shipment is defective. b. A Type I error is not…
In a study conducted by the U.S. Department of Health and Human Services, a sample of 546 boys aged 6–11 was weighed, and it was determined that 87 of them were overweight. A sample of 508 girls aged 6–11 was also weighed, and 74 of them were overweight. Can you conclude that the proportion of boys who are overweight differs from the proportion of girls who are overweight?
Trichotillomania is an illness characterized by the repeated urge to tear out hair, eyelashes, facial hair, nose hair, pubic hair, eyebrows, or other body hair, sometimes resulting in noticeable bald patches. A pharmaceutical company is trying to decide whether to market a drug to treat trichotillomania. The pharmacist who designed the drug believes it is very effective, especially when combined with therapy, whereas a researcher who did research on a sample of people suffering from the disorder is less convinced. Each of them created graphs to support his or her position. Determine whether the pharmacist or the researcher created each graph. (Hint: Decide whether the graph minimizes or maximizes the effect of the drug first. Then decide who would want to do that, and choose your response from the list of possible combinations.)
In an article in the Journal of Advertising, Weinberger and Spotts compare the use of humor in television ads in the United States and in the United Kingdom. Suppose that independent random samples of television ads are taken in the two countries. A random sample of 400 television ads in the United Kingdom reveals that 142 use humor, while a random sample of 500 television ads in the United States reveals that 122 use humor. a) Set up the null and alternative hypotheses needed to determine whether the proportion of ads using humor in the United Kingdom differs from the proportion of ads using humor in the United States. b) Test the hypotheses you set up in part a by using critical values and by setting a equal to .10, .05, .01, and .001. How much evidence is there that the proportions of U.K. and U.S. ads using humor are different?. Please do this stepwise and explanation and also dont do handwritten or skip please!! I will like.
A company manager wants to compare the satisfaction levels of his customers from two stores belonging to his company. According to his research, 249 out of 300 people are satisfied with shop A, and 348 out of 400 people are satisfied with shop B. Which of the following hypothesis states that there is a significant difference between customer satisfaction levels? H0 : P1 < P2, H1 : P1 ≥ P2 H0 : P1 ≥ P2, H1 : P1 < P2 H0 : P1 > P2, H1 : P1 < P2 H0 : P1 = P2, H1 : P1 ≠ P2 H0 : P1 ≠ P2, H1 : P1 < P2
A researcher conducted a medical study to investigate whether taking a low-dose aspirin reduces the chance of developing colon cancer. As part of the study, 1,000 adult volunteers were randomly assigned to one of two groups. Half of the volunteers were assigned to the experimental group that took a low-dose aspirin each day, and the other half were assigned to the control group that took a placebo each day. At the end of six years, 15 of the people who took the low-dose aspirin had developed colon cancer and 26 of the people who took the placebo had developed colon cancer. At the significance level α = 0.05, do the data provide convincing statistical evidence that taking a low-dose aspirin each day would reduce the chance of developing colon cancer among all people similar to the volunteers?
If a researcher finds there is a statistically significant difference, that researcher can automatically conclude that that finding is important in theoretical and/or practical terms. a) True b) False
Let p1 and p2 be the respective proportions of women with iron-deficiency anemia in each of two developing countries. A random sample of 1900 women from the first country yielded 513 women with iron-deficiency anemia, and an independently chosen, random sample of 1700 women from the second country yielded 515 women with iron-deficiency anemia. Can we conclude, at the 0.10 level of significance, that the proportion of women with anemia in the first country is less than the proportion of women with anemia in the second country? Perform a one-tailed test. Then complete the parts below.Carry your intermediate computations to three or more decimal places and round your answers as specified in the parts below. a. State the null hypothesis H0 and the alternative hypothesis H1. b. Find the values of the test statistic. c. FInd the p-value. d. Can we conclude that the proportion of women with anemia in the first country is less than the proportion of women with anemia in the second country?
If the proportion of the population in City A that is over 65 years old is p1 and the proportion of the population in City B that is over 65 years old is p2, what is the null hypothesis for a test to determine if the proportion of the population that is over 65 years old is greater in City A?
A local dairy conducted taste tests of their nonfat and low fat cream cheese spreads at three supermarkets on one Saturday. They asked people to compare a cracker with their low fat spread on it and another cracker with the nationally known brand of the same type of spread. At one supermarket, everyone who came to the testing table, located just inside by the front door, and asked to participate was included. At a second market, only people who appeared to be older teenagers and adults were allowed to participate. The testing table was in the section of the store where paper goods are sold. At the third store, the testing table was in the dairy section and everyone who was asked to participate was included. However, they ran out of one of the products and had to stop the test three hours earlier than they planned. The table below shows how many people were tested at each location and their stated preferences Store A Store B Store C Number tasters = 258Number preferring local brand…
