Is there an association between a person’s level of education and her/his Census awareness? 1. Calculate an appropriate standardized statistic in the context of the study?
A colonoscopy is a medical procedure that is designed to find and remove precancerous lesions in the colon before they become cancerous. The article “Association of Colonoscopy and Death from Colorectal Cancer” reports that in a sample of 10,292 people diagnosed with colorectal cancer, 7.1% had previously had a colonoscopy. In a sample of 51,460 people without colorectal cancer, 9.8% had previously had a colonoscopy. 25.

The Alan Guttmacher Institute Abortion Provider Survey is a survey of all 358 known nonhospital abortion providers in the United States (Perspectives on Sexual and Reproductive Health, Jan./Feb. 2003). For one part of the survey, the 358 providers were classified according to case load (number of abortions performed per year) and whether they permit their patients to take the abortion drug misoprostol at home or require the patients to return to the abortion facility to receive the drug. The responses are summarized in the accompanying table. Suppose we select, at random, one of the 358 providers and observe the provider's case load (fewer than 50, or 50 or more) and home use of the drug (yes or no). Number of Abortions Permit Drug at Home Fewer than 50 50 or more Totals Yes 170 130 300 No 48 10 58 Totals 218 140 358 a. Find the probability that the case load of a provider is fewer than 50, given that the provider permits home use of the abortion drug. b. Find the…

There are 15,958,866 adults in a region. If a polling organization randomly selects 1235 adults without replacement, are the selections independent or dependent? If the selections are dependent, can they be treated as independent for the purposes of calculations? Are the selections independent or dependent? A. The selections are dependent, because the selection is done without replacement. B. The selections are dependent, because the sample size is not small relative to the population. C. The selections are independent, because the sample size is small relative to the population. D. The selections are independent, because the selection is done without replacement. If the selections are dependent, can they be treated as independent for the purposes of calculations? A. Yes, because the sample size is greater than 5% of the population. B. Yes, because the sample size is less than 5% of the population. C.…
