- What is meant by the sample space of an experiment?arrow_forwardConsider the following research questions/study scenarios. For each study, discuss the most appropriate methods for describing the data (graphically and numerically). What statistical method would be most appropriate for addressing the research questions? Be sure to provide justification of the statistical method. When a statistical test is needed, provide appropriate null and research hypotheses. A study investigating the effects of second-hand smoke in working environments asked the following question: “How often do you experience second-hand smoke in a work environment/function? Never, Occasionally, Fairly Often, Very Often, Almost Always.” The question was asked of managers and employees to determine whether there was an association between position and the amount of second-hand smoke exposure. The responses to the questions were grouped into Little/Non and Often, where Little/None was defined as responses of Never or Occasionally and Often was defined as responses of Fairly…arrow_forwardThe researchers looked at 60 people who were infected with coronavirus. 35 of the subjects were vaccinated, of which 5 were seriously ill.

- 1. A poll was taken this year asking college students if they considered themselves overweight. A similar poll was taken 5 years ago. Five years ago, a sample of 270 students showed that 120 considered themselves overweight. This year a poll of 300 students showed that 140 considered themselves overweight. At a 5% level of significance, test to see if there is any difference in the proportion of college students who consider themselves overweight between the two polls.

- Hello, I need help with the following question and its parts. According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in 2007 were for identity theft. In that year, Alaska had 321 complaints of identity theft out of 1,432 consumer complaints ("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 the 5% level. a. Name of Test: b. State the random variable and the parameter in words. c. State the null and alternative hypotheses and the level of significance. d. State and check the assumptions for a hypothesis test. e.

The politician gave four examples of schools that used the program: scores at the schools increased 0.5, 1, 2, and 2.5 points respectively (the nation-wide average of the scores is 70). The politician gave no additional evidence about the effectiveness of the program. Your task: What questions or comments would you have pertaining to the statistical claim made by the politician? You might inquire about the sample, the sampling methods, the full population, the sampling distribution of the mean, and whatever would be useful to more accurately or precisely describe the effectiveness of the program. At the end of your post, state whether you would conclude that the program will increase scores nation-wide. Note that it is a separate question of whether it is "worth it" to effect change by taking money from people in the form of taxes to pay for a program.
