Suppose the Japanese Health Authority conducts a country wide survey to assess if men or women have the same likelihood of getting infected with COVID-19. A random sample of (500 + 90) and 400 women were selected, and 50% of these men and 45% of these women were infected with COVID-19, respectively. What is the 91.98% condence interval for the true dierence in proportion of men and women who get infected with COVID-19.

A research center claims that at least 27% of U.S adults think that the IRS will adult their taxes. In a random sample of 1000 U.S adults in a recent year 23% say they are concerned that the IRS will adult their taxes. At x=0.01, is there enough evidence to reject the center's claim?
An organization published an article stating that in any one-year period, approximately 11.5 percent of adults in a country suffer from depression or a depressive illness. Suppose that in a survey of 100 people in a certain town, nine of them suffered from depression or a depressive illness. Conduct 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 population in the country. At a pre-conceived α = 0.05, what are your following?Decision: , Reason for the decision: ,Conclusion
A large research project showed that in a sample of 750 adults, 60 of them experienced a midlife crisis . Use this data to test the claim that the percentage of adults who experienced midlife crisis is less than 10%. Use (alpha)= 0.05 .
The number of Muslims continues to grow throughout the world, and they are currently thesecond-largest religious group in the world. Knowing that this group has been the target of falsebeliefs about their religion, a researcher is interested in whether people who have moreinteractions with Muslim people are less likely to believe negative statements about Islam. To dothis, they surveyed a large sample of participants across Western Europe and asked themquestions about how frequently they interact with Muslim people as well as how much theyagreed with negative statements about Islam. What statistical test should be used to determine ifthere if how frequently survey participants interact with Muslim people predicts how likely theyare to agree with a negative statement about Islam? Assume parametric assumptions are met. A. Is this a relationship test or a difference test? Explain your rationale. B.
Suppose that in a study on a certain population, it is reported that a rapid molecular COVID-19 diagnostictest yielded a false negative value (sensitivity of the test) of 12% (that is, 88% of tests on people with theCOVID-19 virus correctly detect it) and a false positive value (specificity of the test) of 2% (that is, 98%of the tests on people without COVID-19 correctly conclude that the person is COVID-19 free). Assumethat 16% of the population has COVID-19. If a randomly chosen person is tested and their result showsa positive test, what is the probability that they have COVID-19?
According to a certain government agency for a large country, the proportion of fatal traffic accidents in the country in which the driver had a positive blood alcohol concentration (BAC) is 0.33.Suppose a random sample of 109 traffic fatalities in a certain region results in 47that involved a positive BAC. Does the sample evidence suggest that the region has a higher proportion of traffic fatalities involving a positive BAC than the country at the α=0.05 level of significance?
A recent study was conducted in Santa Clara County, California. Random samples of 3,330 people were tested for the antibody for the SARS-CoV-2 virus, which causes the COVID-19 disease. Fifty (50) of the 3,330 tested positive for the antibody and may have been infected with the virus. Using this data, calculate the proportion of the sample (p) that tested positive for the antibody.
An education researcher claims that at most 3% of working college students are employed as teachers or teaching assistants. In a random sample of 200 working college students, 4% are employed as teachers or teaching assistants. At x=0.01 is there enough evidence to reject the researcher's claim?
In a clinical trial, 29 out of 853 patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that 2.9% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 2.9% of this drug's users experience flulike symptoms as a side effect at the α=0.1 What is the test statistic z0?
Each day for 200 days, a quality engineer samples 144 fuses rated at 15 A and measures the amperage at which they burn out. He performs a hypothesis test of H0 : μ = 15 versus H1 : μ ≠ 15, where μ is the mean burnout amperage of the fuses manufactured that day. a) On 10 of the 200 days, H0 is rejected at the 5% level. Does this provide conclusive evidence that the mean burnout amperage was different from 15 A on at least one of the 200 days? Explain. b) Would the answer to part (a) be different if H0 had been rejected on 20 of the 200 days? Explain.
A researcher is concerned that his new antihypertensive medication may be causing insomnia in some of his patients. Suppose he gathers an SRS of 65 patients treated with the study drug with a sample average of 6.6 hours of sleep and a σ=1.1. Assuming that insomnia can be quantified as an average of 4.5 hours of sleep, can we determine with 95% confidence that his drug avoids diagnosis of insomnia as a side-effect?
A newspaper article reported that people spends a mean of 6 hours per day watching tv, with a standard deviation of 1.8 hours. A psychologist would like to conduct interviews with the 15% of the population who spend the most time watching tv. She assumes that the daily time spent watching tv is normally distributed. At least how many hours of daily tv watching are necessary to be eligible for the interview? Carry intermediate computations to 4 places, and the answer to 1.
