A nonprofit organization conducted a survey of 2140 metropolitan-area teaches regarding their beliefs about problems that hamper students’schooling. The following data were obtained:-900 said that lack of parental support is a problem.-890 said that abused or neglected children are problems. -680 said that malnutrition or students in poor health is a problem-120 said that lack of parental supportand abused or neglected children are problems-110 said that lack of parental support and malnutrition or poor health are problems-140 said that abused or neglected children and malnutrition or poor health are problems-40 said that lackof parental support, abuse or neglect, and malnutrition or poor health are problemsWhatis the probability that a teacher selected at random from this group said that lack of parental support is the only problem hampering students’schooling?
Do ethnic group and gender influence the type of care that a heart patient receives? The following pas- sage is from the article “Heart Care Reflects Race and Sex, Not Symptoms” (USA Today, February 25, 1999, reprinted with permission):Previous research suggested blacks and women were less likely than whites and men to get cardiac cathe- terization or coronary bypass surgery for chest pain or a heart attack. Scientists blamed differences in illness severity, insurance coverage, patient preference, and health care access. The researchers eliminated those differences by videotaping actors—two black men, two black women, two white men, and two white women—describing chest pain from identical scripts. They wore identical gowns, used identical gestures, and were taped from the same position. Researchers asked 720 primary care doctors at meetings of the American College of Physicians or the American Academy of Family Physicians to watch a tape and recommend care. The doctors thought the…

Many delivery trucks feature a "How Am I Driving?” sticker on the rear bumper, along with a phone number. This sticker allows drivers to report erratic driving by the truck driver or offer a compliment if they like. A dispatcher at the trucking station accepts calls and records information from those who call the phone number. The dispatcher reports that in the past month, 218 calls were received. Of those calls, 178 reported negative driving behaviors by the truck drivers. How might this data-collection method produce bias in obtaining an estimate of all drivers who are satisfied with the company’s truck drivers? This sample may lead to nonresponse bias because many drivers may not call the phone number. This sample may lead to undercoverage bias because some drivers will be more likely to be included in the sample. The sample may lead to response bias because some who call the phone number may not provide a truthful opinion. This sample may lead to voluntary response bias because…

2.) The Gallup organization surveyed 1100 adult Americans on May 6-9, 2002, and conducted an independentsurvey of 1100 adult Americans on May 8-11, 2014. In both surveys they asked, “Right now, do you think the stateof moral values in the country as a whole is getting better or getting worse?” On May 8-11, 2014, 816 of the 1100of the survey responded that the state of moral values is getting worse; on May 6-9, 2002, 737 of 1100 surveyedresponded that the state of moral values is getting worse. Is there a significant difference between the twoproportions at the ? = 0.1 level of significance?a.) Verify that the requirements for inference about two population proportions is satisfied.b.) What is the Null and Alternative Hypotheses? What test will you be using?c.) What is the level of significance and the ?-value?
A teacher who is trying to determine if the evidence supports the fact that a new method of teaching economics is more effective than a traditional one will conduct a _____ test. a. multi-tailed b. one-tailed c. paired d. two-tailed
As discussed in the Wall Street Journal story, weighting is designed to adjust poll results to give more weight to people whose demographic characteristics are under-represented in the sample and less weight to people whose demographic characteristics are over-represented. Think about how certain demographic groups might end up being under or over-represented (that is, there are too many or too few people in the sample from that group, compared to the population as a whole). Weighting can therefore potentially help fix which types of bias? (Check all that apply.) selection bias non-response bias response bias
There is some evidence that high school students justify cheating in class on the basis of poor teacher skills or low levels of teacher caring (Murdock, Miller, & Kohlhardt, 2004).Students appear to rationalize their illicit behavior based on perceptions of how their teachers view cheating. Poor teachers are thought not to know or care whether students cheat, so cheating in their classes is okay. Good teachers, on the other hand, do care and are alert to cheating, so students tend not to cheat in their classes. Following are hypothetical data similar to the actual research results. The scores represent judgments of the acceptability of cheating for the students in each sample. Poor Teacher Average Teacher Good Teacher n = 6 M = 6 n = 8 M = 2 n = 10 M = 2 N = 24 G = 72 SS = 30 SS = 33 SS = 42 ΣX2 = 393 a. Use an ANOVA with α = .05 to determine whether there are any significant differences in student judgments depending on…
