A recent report claimed that 13% of students typically walk to school. DeAnna thinks that the proportion is higher than 0.13 at her large elementary school. She surveys a random sample of 100 students and finds that 17 typically walk to school. DeAnna would like to carry out a test at the a = 0.05 significance level of Но : р %3D 0.13 На : р> 0.13 where = the true proportion of all students at her elementary school who typically walk to school. What conclusion would you make? Because the P-value of 0.1170 > a = 0.05, we fail to reject Ho. We have convincing evidence that the true proportion 0• of all students at this elementary school who typically walk to school is greater than 0.13. Because the P-value of 0.1170 > a = 0.05, we fail to reject Ho. We do not have convincing evidence that the true proportion of all students at this elementary school who typically walk to school is greater than 0.13. Because the P-value of 0.1170 > a = 0.05, we reject Họ. We do not have convincing…

A recent college graduate is trying to decide whether or not pursuing a Master's degree is worth it. He decides examine this question at the a 0.05 level of significance, by comparing the salaries of a random sample of adults with only a Bachelor's degree to a random sample of adults with a Master's degree to see if the adults with a Master's degree earn more money. Let uB represent the average salary of an adult with a Bachelor's degree only and uM represent the average salary of an adult with a Master's degree. Which would be correct hypotheses for this test?

1. Suppose we are interested in the relationship between individuals’ place of residence (rural versus urban) and their political affiliation (Republican versus Democrat). A random sample of 100 individuals yields the following crosstabulation: Political Affiliation Place of Residence Republican Democrat Rural 21 29 Urban 14 36 A. In words, what is the null hypothesis to be tested? B. Is the relationship between place of residence and political affiliation statistically significant at the .05 level? (Be sure to show the statistics that lead to your decision.) C. Compute and interpret an appropriate measure of association for the relationship between these two variables. D. Using the typical rules of thumb, would you say…

1.) After conducting a clinical trial to assess the effect of pharmaceutical eye drops (Eyezican) on glaucoma, researchers found an RR of 2.7 (95% CI, 0.1-4.4). The true association between the drops and glaucoma is actually RR = 1.3. a. Discuss the results in the context of precision, validity, strength of association, and statistical significance (4-5 sentences). b. Describe one element in the study that could be changed by researchers to increase precision.
