Determine whether the study is an experiment or an observational study, and then identify a major problem with the study.A sociologist has created a brief survey to be given to 2000 adults randomly selected from the U.S. population. Here are her first two questions: (1) Have you ever been the victim of a felony crime? (2) Have you ever been convicted of a felony?This is anV because the researcherV the individualsWhat is a major problem with the study?O A. The sample includes only U.S. adults.O B. There is no blinding or replication, which has a high chance of leading to bias.OC. Individuals convicted of a felony are more likely to not answer the second question honestly.O D. The responses will be voluntary, which will lead to a high chance of bias.

Athabasca Fishing Lodge is located on Lake Athabasca in northern Canada. In one of its recent brochures, the lodge advertises that 75% of its guests catch northern pike over 20 pounds. Suppose that last summer 65 out of a random sample of 84 guests did, in fact, catch northern pike weighing over 20 pounds. Does this indicate that the population proportion of guests who catch pike over 20 pounds is different from 75% (either higher or lower)? Use? = 0.05 . Is the sample size large enough to approximate distribution using Normal distribution? WHY?.b. What are the hypotheses?

Wal-Mart wants to introduce a new subscription service (called Plum) that would result in customers getting free two-day delivery. Wal-Mart introduces Wal-Mart Plum to a random sample of 99 customers. You are hired by Wal-Mart to analyze if the introduction of Plum andtwo-day delivery increases sales for Wal-Mart. You find that the 99 random customers that were offered Plum Two Day Delivery spent $2,500 per year on Wal-Mart with a sample standard deviation of $500 in sales. (A) Test whether the sales of Wal-Mart Plum are statistically different from zero at an alpha of 1% (99% confidence level). Set up your null and alternative hypotheses. Test at the 1% level of significance. Show your test and critical statistics. Are the sales for Two-Hour Plum Delivery statistically different from 0? Interpret your answer. Show your work (B) Suppose the typical Wal-Mart consumer spends $2000 a year. Test whether the introductionof Wal-Mart Plum Delivery increased sales. Set up your null and…

Source: the federalist.com "According to a new Gallup poll released Wednesday [3/25/20], the media was the only institution that scored a negative approval rating among the public with only 44 percent of Americans approving of the way the media has covered the [Corona]virus. The poll was conducted March 13-22 and surveyed a random sample of 1,020 adults through telephone interviews aged 18 and older in each state and the District of Columbia." Calculate and interpret a 99% confidence interval for the true proportion of all Americans who approve of the way the media has covered the virus.

One of the problems encountered by corporations in America is finding an adequate number of employees who want to move into management. Recent surveys of workers in America taken by the Department of Labor in Washington D. C. revealed that only 20% of employees would like to move into management and be the boss. Suppose that a random sample of 75 U.S. workers was taken and each person was asked whether or not they would like to move into management. In addition, suppose that the above random sample actually showed that only 11 of the 75 sampled employees would like to move into management. Do you think this data indicates that the Department of Labor has overstated the percentage of workers who would like to move into management? Select the best answer. You may assume the mean of the distribution is 15 and the standard deviation is 3.4641. One of the problems encountered by corporations in America is finding an adequate number of employees who want to move into management. Recent…
Consider an experiment for patients who underwent CPR for a heart attack and then was sent to the hospital. Patients were randomly divided into a treatment group where they received a blood thinner or the control group where they did not. We're interested in understanding what proportion of patients survived in the first 24 hours in the hospital. Here's the data: Control Treatment Survived 11 14 Died 39 26 With the help of Mathematics and R Studio: Conduct a (full) hypothesis test to determine if the treatment group survived at a higher rate than the control group.
