A blog noted that "there has been increasing anecdotal evidence that vitamin C may still be useful as an anticancer medicine if used in high concentrations and given directly into the vein (intravenously)." Use this information to answer the questions below. Question content area bottom Part 1 Explain what it means that there is "increasing anecdotal evidence" that Vitamin C may be a useful anticancer medicine. A. There is no evidence that shows Vitamin C may be a useful anticancer medicine. B. There is scientific evidence that Vitamin C is a non-useful anticancer medicine. C. There is an increase in rigorous or scientific analysis that shows Vitamin C may be a useful anticancer medicine. D. There is an increase in observations or personal experiences that shows Vitamin C may be a useful anticancer medicine. Part 2 How does anecdotal evidence contrast with scientific evidence? A. They are stories about individual cases.…
Pregnant women are screened for a birth defect called Down syndrome. Down syndrome babies are mentally and physically challenged. Some mothers choose to abort the fetus when they are certain that their baby will be born with the syndrome. The most common screening is maternal serum screening, a blood test that looks for markers in the blood to indicate whether the birth defect may occur. The false-positive and false-negative rates vary according to the age of the mother. Mother’s Age False-Positive Rate False-Negative RateUnder 30 0.040 0.37630-34 0.082 0.29035-37 0.178 0.269Over 38 0.343 0.029 The probability that a baby has Down syndrome is primarily a function of the mother’s age.

Does reading the Harry Potter books encourage tolerance? It depends. Italian fifth graders were (randomly) split into two groups. Half the students met with researchers and discussed passages from the Harry Potter books that handled prejudice, while the others talked about unrelated sections. *Data are fabricated but match actual results When determining whether or not the main effects and interactions were significant, for the sake of this assignment, let’s say that the difference between the calculated means/differences must be .7 or higher to be significant. Posttest attitudes toward immigration (7-pt scale) Discussed prejudice-related sections Discussed unrelated sections High identification w/ Harry 6.2 5.0 Low identification w/ Harry 4.2 4.4 Is there a main effect of identification?

You are part of a trivia team and have tracked your team's performance since you started playing, so you know that your scores are normally distributed with u = 76 and o = 12. Recently, a new person joined the team, and you think the scores have gotten better. The sample data is n = 12, sample mean = 86 Assuming a one tailed test, What is the test statistic?
Professor Chase from the University of Kansas has been working on a new cholesterol medication that is being called CholestoCleaner. The university is now conducting studies to determine if there is a possible side effect of sore joints. Placebo (Population Rate) To help determine the usual rate of sore joints, the research team gave a placebo (sugar pill) to 2017 subjects. Of those 2017 subjects, 4 of them developed sore joints. CholestoCleaner Trial The CholestoCleaner drug was given to 2622 subjects. Of those 2622 subjects, 19 of them developed sore joints. Preliminary Math If we consider the general population of people that don't use CholestoCleaner, what is the probability that they will develop sore joints? (Enter your answer as a fraction.) If you had a sample size of 2622 that did NOT use CholestoCleaner, how many would expect to develop sore joints? When 2622 subjects DID use the drug, there were 19 subjects that developed sore joints. Does it seem as though sore joints…
