A study was conducted simultaneously in two different communities in New York City to examine an association between variable A and variable B. The resulting analysis yielded two different p-value in the two communities? Study in Community A yielded a p-value of 0.01. Study in Community B yielded a p-value of 0.05. Which of the above values provides a stronger indictment of the null hypothesis? A. 0.01 B. 0.05

State the null and alternative hypothesis: 1. An aerobics instructor believes that regular exercise is related to greater mental acuity, stress reduction, high self- esteem, and greater overall life satisfaction. She recruits a random sample of 10 adults to participate in her study. Each subject is asked to fill out a series of questionnaires. The results are as follows. Test for the significant association between regular exercise and each of the different factors. 2. Test for the significant relationship between nurses’ satisfaction and nurses’ efficiency 3. Fifteen students are given a test of a general ability and a Math achievement test with the resulting scores: Test for the significant association between general ability and match achievement
4.44 Nearsighted: It is believed that nearsightedness affects about 8% of all children. In a random sample of 194 children, 21 are nearsighted. Conduct a hypothesis test using the 5% significance level. a) Construct hypotheses appropriate for the following question: Do these data provide evidence that the 8% value is inaccurate? O Ho:p = 0.08 HA:P + 0.08 Но:р — 0.08 НА:р> 0.08 O Ho:p = 0.08 НА:р < 0.08 b) What proportion of children in this sample are nearsighted? Round your answer to 4 decimal places. c) Given that the standard error of the sample proportion is 0.0195 and the point estimate follows a nearly normal distribution, calculate the test statistic (use the z-statistic). Round your answer to 2 decimal places. d) What is the p-value for this hypothesis test? Round your answer to 4 decimal places. p =
A study of seat belt users and nonusers yielded the randomly selected sample data summarized in the accompanying table. Use a 0.05significance level to test the claim that the amount of smoking is independent of seat belt use. A plausible theory is that people who smoke are less concerned about their health and safety and are therefore less inclined to wear seat belts. Is this theory supported by the sample data? Number of Cigarettes Smoked per Day 0. 1-14. 15-34. 35 and over Wear Seat Belts. 158. 29. 41. 6 Don't Wear Seat Belts 160. 20. 30 8 Determine the null and alternative hypotheses. A.

Results on seat belt usage from the 2003 Youth Risk Behavior Survey were published in a USA Snapshot on January 13, 2005. The following table outlines the results from the high school students who were surveyed in the state of Nebraska. They were asked whether or not they rarely or never wear seat belts when riding in someone else's car. Using ? = .05, does this sample present sufficient evidence to reject the hypothesis that gender is independent of seat belt usage?
