- What is meant by the sample space of an experiment?The Pew Research Center has reported results of many studies highlighting political topics and potential public policy. For example, when Gallup first surveyed public opinion about the legalization of marijuana in 1969, only 12% of the public favored legalization. A more recent survey from March 2016 showed 53% of the public favoring legalization of marijuana. To examine potential generational differences in the proportions who favor the legalization of marijuana, researchers randomly surveyed groups of Baby Boomers (those born between 1946 and 1964) and Millennials (those born from 1981 to 1997) asking the following question: "Do you support the legalization of marijuana for medical and recreational use in the United States?" The data were as follows. Yes No Total Baby Boomers (population 1) 312 293 605 Millennials (population 2) 349 286 635 (a) State the appropriate null and alternative hypotheses.

Millions more are designated as overweight.” The American trend toward obesity has prompted many physicians to offer weight-loss programs to their patients. [Source: Price, W. T. “Physicians Get into the Weight-Loss Business.” Florida Today, July 7, 2008.] A physician conducted an experimental study to compare the effectiveness of four different weight-loss programs. In the study, 64 obese adults were randomly assigned to the four programs so that each program had 16 adults. The programs lasted for six months. The weights of the subjects were measured before and after the programs, and each subject’s weight loss was computed in pounds. The following table summarizes the results of the study, giving the number of observations and the sample mean and variance of the subjects’ weight loss in each program.…
- 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 lower proportion of identity theft than 23%? Test at the 5% level.A random sample of 1100 potential voters was randomly divided into 2 groups. Group 1: 500 potential voters; no registration reminders sent; 248 registered to vote Group 2: 600 potential voters; registration reminders sent; 332 registered to vote Do these data support the claim that the proportion of voters who registered was greater in the group that received reminders than in the group that did not? Use a 1% level of significance.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.

- Researchers in a California community have asked a sample of 175 automobile owners to select their favorite from three popular automotive magazines. Of the 111 import owners in the sample, 54 selected Car and Driver, 25 selected Motor Trend, and 32 selected Road & Track. Of the 64 domestic-make owners in the sample, 19 selected Car and Driver, 22 selected Motor Trend, and 23 selected Road & Track. What is the value of the Chi-square statistic?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.
