What’s is the the primary factor in determining homosexuality? What’s is the the primary factor in determining homosexuality? What’s is the the primary factor in determining homosexuality? Ravre for the al eview 07 1. Cleanliness The American Society for Microbiology and the Soap and Detergent Associa tion released survey resuls indicating that among 3065 men observed in public restrooms 2023 of them washed their hands, and among 3011 women observed, 2650 washed their hands (based on data from USA Today. a. Is the study an experiment or an observational scudy b. Are the given numbers discrete or continuous? c. Are the given numbers statistics or parameters? d. Is there anyching about the study that might make the resuls questionable Golf Scores Listed below are first round and fourth round golf scoves of randomly selected golfers in & Professional Golf Association Championship (based on data from the New York Timel). Find the mean, median, range, and standard deviation for the first round scores, then find those same statistics for the fourth round scores. Compare the results Fins round 71 68 75 72 74 67 Fourth round69 69 69 72 70 73 . Golf Scores Refer to the ample daca given in Exercise . Ue a 005 significance level to test for a linear correlation between the first round scores and the fourth round scores . Golf Scores Using only the first round golfcores given in Exercise 4, construct a 95% confidence interval extimate of the mean first round golf score for all golfern. Interprer the result . Ergonomics When designing the cockpit of a single-engine aircraft, engineers must con- sider the upper leg lengths of men. Those lengths are ormally disuibuted with a mean of 42.6 cm and a standard deviation of 2.9 cm (based on Data Set 1 in Appendix B). a. If one man is randomly selected, find the probability that his upper leg length is greater than 45 cm b. If 16 men are randomly selected, find the probabiliy that cheir mean upper leg length is greater than 45 cm. e. When designing the airaraft cockpit, which result is more meaninghul: the result from part (a) or the result from part (b)? Why? ?Body mass i da measurementsof adults are normally distributed with a mean of 26 and a standard deviation of 5 (based on Data Set 1 in Appendix B), Is a body mass index of 40 an outlier? Why or why not t. Body mass index measurements of aduls are normally distributed with a mean of 26 and a standard deviation of 5 (based on Data Set 1 in Appendix B) a. Find the probability of randomly selecting a person with a body mass index greater than 28. b. If 16 people are randomly selected, find the probability that their mean body mass index is greater than 28.Explanation / Answer
1a. The study is observational in nature as there has been no manipulation of variables.
1b. The given numbers are discrete as these are variables whose value can be obtained by counting.
1c. The given numbers are statistics as they are data of the sample and not the population.
1d. I would question the ethical aspect of the data because restrooms are highly private settings and studies should not install any recording tools without the permission of the user.
