- The article “HIV-positive Smokers Considering Quitting: Differences by Race/Ethnicity” (E. Lloyd-Richardson, C. Stanton, et al., Am J Health Behav, 2008:3–15) reported that in a group of 230 European-American HIV-positive smokers, 102 of them had used a nicotine patch to try to quit smoking, and in a group of 72 Hispanic-American HIV-positive smokers, 20 had used a nicotine patch. Can you conclude that the proportion of patch users is greater among European-Americans?The following table was presented in an article summarizing a study to compare a new drug to a standard drug and to a placebo.

- To determine current attitudes of parents concerning whether or not teachers should take a mandatory COVID-19 test to teach at schools, a survey was conducted in four public schools. The following table gives the attitudes of 550 parents surveyed: School 1 School 2 School 3 School 4In Favor 65 66 40 34Oppose 42 30 33 42No Opinion 93 54 27 24 Test whether there is an association between the School and the attitude towards mandatory COVID19 test at 1% level of significance.The paper “Contemporary College Students and Body Piercing” (Journal of Adolescent Health [2004]: 58-61) described a survey of 450 undergraduate students at a state university in the southwest region of the United States. Each student in the sample was classified according to class standing (freshman, sophomore, junior, or senior) and body art category (body piercings only, tattoos only, both tattoos and body piercings, no body art). Use the data in the accompanying table to determine if there is evidence that there is an association between class standing and response to the body art question. Assume that it is reasonable to regard the sample of students as representative of the students at this university. Use α = .01.s there a relation between incidents of child abuse and number of runaway children? A random sample of cities (over 10,000 population) gave the following information about the number of reported incidents of child abuse and the number of runaway children.

- A foundation asked each person in a representative sample of high school students and in a representative sample of high school teachers which of the rights guaranteed by the First Amendment they thought was the most important. Suppose that the sample size for each sample was 1,000. Data consistent with summary values from the study are summarized in the accompanying table. Most Important First Amendment Right Freedom of Speech Freedom of the Press Freedom of Religion Freedom to Peacefully Assemble Freedom to Petition the Government Students 655 30 250 20 45 Teachers 400 60 420 50 70 A button hyperlink to the SALT program that reads: Use SALT. (a) Carry out a hypothesis test to determine if there is convincing evidence that the proportions falling into the five First Amendment rights categories are not the same for teachers and students. Use a significance level of ? = 0.01.A statistical program is recommended. Jensen Tire & Auto is in the process of deciding whether to purchase a maintenance contract for its new computer wheel alignment and balancing machine. Managers feel that maintenance expense should be related to usage, and they collected the following information on weekly usage (hours) and annual maintenance expense (in hundreds of dollars). Weekly Usage(hours) AnnualMaintenanceExpense 13 17.0 10 22.0 20 30.0 28 37.0 32 47.0 17 30.5 24 32.5 31 39.0 40 51.5 38 40.0 #1) Develop the estimated regression equation that could be used to predict the annual maintenance expense (in hundreds of dollars) given the weekly usage (in hours). (Round your numerical values to two decimal places.) #2) The expected expense of a machine being used 34 hours per week is $ hundred.Is there a relation between police protection and fire protection?
