A survey was conducted of newlyweds in a country who have a spouse of a different race or ethnicity from their own. The survey included random samples of 1000 newlyweds in Ethnicity A and 1000 newlyweds in Ethnicity B. In the survey, 13%of respondents in Ethnicity A and 24% of respondents in Ethnicity B had a spouse of a different race or ethnicity from their own. At a= 0.01, is there evidence to support the claim that the proportion of newlyweds in Ethnicity A who have a spouseof a different race or ethnicity from their own is less than the proportion of newlyweds in Ethnicity B that have a spouse of a different race or ethnicity from their own?Let p, represent the proportion of newlyweds in Ethnicity A who have a spouse of a different race or ethnicity from their own.

Theres a sampled of 361 people in total. People were allowed to self-identify as a heavy smoker or a non-smoker (mutually exclusive outcomes), and as diagnosed with lung cancer or not diagnosed with lung cancer (mutually exclusive outcomes). All surveyed people were under the age of 55, with similar age distributions in the smoking and not smoking categories. 343 people said that they did not smoke, and of those 343 people, 58 had been diagnosed with lung cancer. Only 18 people said that they were heavy smokers, and of those 18, 14 had been diagnosed with lung cancer. A. A chi-squared test of independence yields a p-value of 2e-9. Assuming an alpha of 0.05, what can you conclude from the data based solely on the chi-squared test? Explain. B. 95% Cl of odd ratios (OR) of odds (cancer / smoking) / odds (cancer /no cancer ) is 5.1 -73.5. What can you conclude based solely on the odds?
The drug X is marketed to help protect against male pattern baldness, and it also may protect against prostate cancer. A large sampleof healthy men over age 60 were randomly assigned to receive either a daily drug X pill or a placebo. The study lasted nine years and the men had annual check-ups and a biopsy at the end of the study. Prostate cancer was found in 815 of 4368 men taking drug X and in 1176 of the 4698 men taking a placebo. What kind of a study is this and what mesure of assocation (rd, rr, or) can be used and why?

A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 305305 people over the age of 55, 6666 dream in black and white, and among 306306 people under the age of 25, 1717 dream in black and white. Use a 0.010.01 significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. Complete parts (a) through (c) below. a. Test the claim using a hypothesis test.

USA Today (Feb. 17, 2011) described a survey of 1,008 American adults. One question on the survey asked people if they had ever sent a love letter using e-mail. Suppose that this survey used a random sample of adults and 205 stated that they had written a love letter using e-mail. Is this evidence that more than 20% of American adults have written a love letter using e-mail? Use a level of significance of 5%. a) p: (3 decimal places) b) Complete the following areas.

In 2001, the Gallup poll found that 81% of American adults believed that therewas a conspiracy in the death of President Kennedy. In 2013, the Gallup pollasked 1,039 American adults if they believe there was a conspiracy in theassassination, and found that 634 believe there was a conspiracy ("Gallup newsservice," 2013). Do the data show that the proportion of Americans who believein this conspiracy has decreased? Test at the 1% level.
An SRS of 250 male faculty at a large university found that 110 felt that the university was supportive of female and minority faculty. An independent SRS of 200 female faculty found that 70 felt that the university was supportive of female and minority faculty. Let pmpmpmpm and pfpfpfpf represent the proportion of all male and female faculty, respectively, at the university who felt that the university was supportive of female and minority faculty at the time of the survey. Is there evidence that the proportion of male faculty members who felt the university was supportive of female and minority faculty is larger than the corresponding proportion for female faculty members? Use α=0.10 A) Were the data appropriately collected for performing a two-sample z test on proportions? Group of answer choices No, because the 450 subjects in the study were not randomly allocated to one of the two treatment groups. Yes, because separate simple random samples were selected from the male and…

In a random survey of 500 men who asked a woman's father for permission before asking the woman for her hand in marriage, 143 said the marriage ended in divorce. In a random survey of 500 men who did not first ask a woman's father for permission, 169 of the marriages ended in divorce. Is there convincing evidence at 5% level, that men who ask a woman's father for permission before asking the woman have marriages with lower divorce rates?
