Each respondent was given a score, from 1 to 15, on his or her knowledge of the COFLU-20. A score from 1 to 7 was considered to indicate 'poor' knowledge, 8 to 11 indicated 'satisfactory' knowledge and 12 to 15 indicated good knowledge. Table 2 below shows the knowledge level of respondents, by age group. Table 2 Age Group Knowledge Level Total Poor Satisfactory Good 18 - 25 33 16 13 62 26 - 34 30 18 12 60 35 - 44 29 14 12 55 45 - 54 36 16 18 70 55 - 75 Total 17 14 22 53 145 78 77 300 (c) Using Table 2, assist the researcher to calculate the probability that a randomly selected respondent: ) is below 35 years of age and has good knowledge of the COFLU-20 [2 marks] (ii) is below 35 years of age or has good knowledge of the COFLU-20 [3 marks]

In a study of high school students at least 16 years of age, researchers obtained the survey results summarized in the table below (based on data from “Texting While Driving and Other Risk Motor Vehicle Behaviors Among U.S. High School Students” by O’Malley, Shults, and Eaton, Pediatrics, 131, No.6). Irregular Seat Belt Use? Yes No RT Texted While Driving 1737 2048 3785 Did not Text While Driving 1945 2775 4720 Column total 3682 4823 8505 State the null and alternative hypotheses. Null hypothesis: H0 Texting when driving is independent of irregular seat belt use. Alternative hypothesis: Texting when driving is dependent of irregular seat belt use. Assuming independence, what are the expected frequencies for each of these variables? E=(row total)(column total) (grand total) What is the value of the X2 statistic? X2=E(0-E)2…

Researchers wanted to determine if having a computercomputer in the bedroom is associated with obesity. The researchers administered a questionnaire to 394394 twelve-year-old adolescents. After analyzing the results, the researchers determined that the body mass index of the adolescents who had a computercomputer in their bedroom was significantly higher than that of the adolescents who did not have a computercomputer in their bedroom. Complete parts (a) through (e) below.(a) Why is this an observational study? What type of observational study is this? Why is this an observational study? A.The researchers administered a questionnaire to obtain their data without trying to influence an explanatory variable of the study. B.The researchers observed the behavior of the individuals in the study without trying to influence an explanatory variable of the study. C.The researchers tried to influence the outcome of the study. D.The researchers intentionally changed an explanatory…
A state fisheries commission wants to estimate the number of bass caught in a given lake during a season in order to restock the lake with the appropriate number of young fish. The commission could get a fairly accurate assessment of the seasonal catch by extensive “netting sweeps" of the lake before and after a season, but this technique is much too expensive to be done routinely. Therefore, the commission samples a number of lakes and record the seasonal catch (thousands of bass per square mile of lake area) and size of lake (square miles). A simple linear regression was performed and the following R output obtained. Estimate Std. Error t value Pr(>|t|) (Intercept) 2.5463 0.4427 5.7513 0.0000 size 0.0667 0.3672 0.1818 0.8578 If a scatterplot showed a non-linear relationship between the response and explanatory variables, what should be done?

A municipality’s local election board claims that 25% of registered voters typically cast ballots in annual school board elections. The local school board believes this percentage of participating voters is, in reality, much lower. What is the population parameter under consideration? What hypotheses should the local school board test in this situation?
