The scientific productivity of major world cities was the subject of a recent study. The study determined the number of scientific papers published between 1994 and 1997 by researchers from each of the 20 world cities, and is shown below. City Number of papers City Number of papers City 1 15 City 11 30 City 2 22 City 12 55 City 3 20 City 13 25 City 4 20 City 14 55 City 5 23 City 15 10 City 6 21 City 16 15 City 7 99 City 17 77 City 8 24 City 18 22 City 9 24 City 19 22 City 10 33 City 20 29 Construct a 9090 % confidence interval for the average number of papers published in major world cities. _______<μ<________
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…
3) A Chi-square test can be done to test all of the following EXCEPT which of the following? If the mathematical model accurately predicts the pattern of data values observed. If the mathematical model accurately predicts the total number of values observed. If traits exhibit independence with regards to the probability of seeing their combinations in individuals in a population. If individuals from different populations have the same probability of possessing various traits. If the mathematical model accurately predicts the proportions of data values observed.

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.

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?
