- According to the February 2008 Federal Trade Commission report on consumerfraud and identity theft, 23% of all complaints in 2007 were for identity theft. Inthat year, Arkansas had 1,601 complaints of identity theft out of 3,482 consumercomplaints ("Consumer fraud and," 2008). Does this data provide enoughevidence to show that Arkansas had a higher proportion of identity theft than23%? Test at the 5% level.According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in the U.S. in 2007 were for identity theft. In that year, Alaska had 321 complaints of identity theft out of 1,432 consumers ("Consumer fraud and," 2008). Does this data provide enough evidence to show that Alaska had a different proportion of identity theft than 23%? Test at 5% level.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. 0.272

A random survey of 100 undergraduate students, 50 postgraduate students and 50 teaching staff were selected with the following results: Opinion Undergraduate Graduate Student Lecturers Disagree 64 28 31 Agree 36 22 19 Total 100 50 50 At the significance level α = 0.05, test whether there is evidence of a difference in opinion (attitude) towards the proposed face-to-face lecture in 2021 among these various groups!The Joint Commission on Accreditation of Healthcare Organizations mandated that hospitals ban smoking by 1994. To study the effects of this ban on smoking behaviors, subjects were randomly selected from two different populations: those from hospitals with the ban and those from hospitals without the ban. Investigators were interested in determining if this smoking ban had any impact on the proportion of smokers employed at each hospital that then quit smoking. Among 843 smoking employees of hospitals with the smoking ban, 56 quit smoking during the study period. Among 703 smoking employees from workplaces without the smoking ban, 27 quit smoking during the study period. Below is the Stata output that was run to determine if there was a statistically significant difference between these two proportions at the α=0.05 level. A. What is the estimate of the proportion of smokers from the hospitals that implemented the ban that quit smoking (the blank labeled "C" in the above output)?…

The study involved assigning a sample of 311 patients to a prepaid medical plan and a sample of 310 patients to the traditional Medicaid program. After a specified period of time, the number of persons in each group who had visited a community crisis center in the previous three months was determined. Among the subjects assigned to the prepaid plan, 13 had visited a crisis center; among those receiving traditional Medicaid, 22 had visited a crisis center. Using Stata, determine how much power you have to detect the observed difference at the 5% significance level.Mechanical engineer Kwok Wai Tham of the National University of Singapore set out to sample how much virus COVID-19 patients produce when they breathe, talk or sing, in part, to address skeptics’ concerns. “I’m doing this to convince some very close friends,” he says. He and colleagues rolled a mobile lab into 22 patients’ rooms and had volunteers stick their heads into a large metal cone. The researchers collected both aerosols and larger droplets that the patients exhaled while breathing quietly for 30 minutes, while repeating passages from Dr. Seuss’ Green Eggs and Ham for 15 minutes, or while singing simple tunes like the “Happy Birthday” song, “Twinkle, Twinkle Little Star” or the “ABCs” for 15 minutes. The scientists tested both aerosols and large droplets in the air samples for coronavirus RNA and calculated how many copies of the virus’s nucleocapsid protein gene, or N gene, were present. That gives an estimate of how much virus is in a sample.Of the 22 patients who sang for…
- A sports betting company is testing the effectiveness of its online ads and has developed a classification model that predicts whether a potential customer will respond to its offer using information in the potential customer's browser history (cookies, etc.). Out of a test dataset of 1,000 customers, the 100 customers most likely to respond (according to the model) are identified and it is discovered that 14 of these actually did respond to the online ads. In the entire test dataset of 1,000 customers, only 39 customers responded to the ad. What is the lift of the classification model for the set of 100 customers it identified as most likely to respond? If required, round your answer to two decimal places. I got 3.59 as the answer and its incorrect.A closed cohort study was conducted to investigate whether or not diabetes increases the risk of heart disease. During the enrollment period over 3,000 individuals were interested in participating and were screened for eligibility. Of those, 2,556 were eligible and enrolled. 216 of the participants had diabetes and 2,340 did not have diabetes at time of enrollment. During the 20 year follow up period, among those who had diabetes, 26 developed coronary heart disease. Among those who did not have diabetes, 91 developed coronary heart disease. Question 1) Calculate and interpret the appropriate measure of disease occurrence and measure of association for this cohort study. Question 2) Calculate the Risk Difference to get an idea of how much risk of disease would be preventable if you "eliminate" diabetes. How do you interpret and communicate your findings? Based on establish knowledge about the etiology of disease, the investigators want to consider hypertension as a…Suppose you are asked to sample 100 students at the University to get their opinions about a requirement that all students get Covid-19 vaccine before resuming inperson classes in the Fall 2021.a) Describe how you could go about getting a stratified sample. b) Describe how you could go about getting a voluntary response sample
