Effect of Blinding Among 13,200 submitted abstracts that were blindly evaluated (with authors and institutions not identified), 26.7% were accepted for publication. Among 13,433 abstracts that were not blindly evaluated, 29.0% were accepted (based on data from “Effect of Blinded Peer Review on Abstract Acceptance,” by Ross, et al., Journal of the American Medical Association, Vol. 295, No. 14). Use a 0.01 significance level to test the claim that the acceptance rate is the same with or without blinding. How might the results be explained?

- What is meant by the sample space of an experiment?arrow_forwardWhat is an experiment?arrow_forwardWeather-Related Deaths Review Exercise 5 involved weather-related U.S. deaths. Among the 450 deaths included in that exercise, 320 are males. Use a 0.05 significance level to test the claim that among those who die in weather-related deaths, the percentage of males is equal to 50%. Provide an explanation for the results.arrow_forward
- Smoking Stopped In a program designed to help patients stop smoking, 198 patients were given sustained care, and 82.8% of them were no longer smoking after one month (based on data from “Sustained Care Intervention and Postdischarge Smoking Cessation Among Hospitalized Adults,” by Rigotti et al., Journal of the American Medical Association, Vol. 312, No. 7). Use a 0.01 significance level to test the claim that 80% of patients stop smoking when given sustained care. Does sustained care appear to be effective?arrow_forwardPlease help with D E and F and Garrow_forwardWhat is the alternative hypothesis?arrow_forward
- The Survey of Study Habits and Attitudes (SSHA) is a psychological test designed to measure various academic behaviors (motivation, study habits, attitudes, etc…) of college students. Scores on the SSHA range from 0 to 200. The data for random samples 18 women (*the outlier from the original data set was removed) and 27 men yielded the following summary statistics.Is there a difference in SSHA performance based upon gender? Conduct the appropriate hypothesis test in including stating the relevant hypothesis, test statistic, p-value, and conclusion. Then, construct and interpret a 90% confidence interval for the mean differencearrow_forwardWhat is the best correlational test to use in SPSS for a research sample size of 39?arrow_forwardConsider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 6107 patients treated with this drug, 158 developed the adverse reaction of nausea. Use a 0.05 significance level to test the claim that 3% of users develop nausea. Does nausea appear to be a problematic reaction?arrow_forward
- Consider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 6130 patients treated with this drug, 160 developed the adverse reaction of nausea. Use a 0.10 significance level to test the claim that 33% of users develop nausea. Does nausea appear to be a problematic adverse reaction?arrow_forwardSuppose 214 subjects are treated with a drug that is used to treat pain and 53 of them developed nausea. Use a 0.10 significance level to test the claim that more than 20% of users develop nausea.arrow_forwardWhich of these sounds like a situation where you would want to use an Independent-Measures ANOVA? A) Comparing the health of students at a campus with a Student Health Center vs. students at a campus without a Student Health Center B) Comparing the technological ability of a group of children when they are 10 years old vs. when they reach 15 years old vs. when they reach 20 years old C) Comparing the pain levels of people with an anti-arthritis drug vs. the pain levels of the general population of all arthritis patients D) Comparing the technological ability of three groups: people born in the years 2000, 2005 and 2010arrow_forward
