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…

Suppose that a survey was carried out in New York, and each respondent was faced with the following two questions:a. Is the last digit of your Social Security number odd?b. Have you ever lied on an employment application?The second question is, of course, quite sensitive, and for various reasons we might expect that a number of people would not answer the question honestly, especially if their response were yes. To overcome this potential bias, respondents were asked to flip a coin and then to answer question (a) if the result was “head” and answer (b) otherwise. A yes response was given by 37% of all respondents. What is the probability that a respondent who was answering the sensitive question, (b), replied yes?

An article noted that chocolate is rich in flavonoids. The article reports that​ "regular consumption of foods rich in flavonoids may reduce the risk of coronary heart​ disease." The study received funding from a candy company and a chocolate manufacturers association. Identify and explain at least one source of bias in the study described. Then suggest how the bias might have been avoided.       Choose the correct answer below.     A. The researchers may have been more inclined to provide favorable results because funding was provided by a party with a definite interest. The bias could have been avoided if the researchers were not paid by the candy company and the chocolate manufacturers.   B. The data do not seem to support the claims being made by the article. The​ article's author should consult an expert to make sure that he or she is correctly interpreting the​ study's results.   C. Since the sample is​ self-selected, there is a definite participation bias in…

Sierra College students enrolled in an online Elementary Statistics course were asked to participate in an anonymous onlne survey. The survey asked the students "Which type of device will you primarily use to access your online course in Canvas?". Of the 152 students who answered this question, 20 responded "a desktop computer", 121 responded "a laptop computer", 6 responded "a smartphone", and 5 responded "a tablet". The Sierra College Mathematics Department believes that less than 5% of students enrolled in an online Elementary Statistics course primarily uses a smartphone to access their online course in Canvas. Use the data collected in the survey to conduct a hypothesis testing procedure to test this belief. What conclusion should be reached according to the results of this hypothesis test?

1. In general terms, what is a hypothesis test?   a. A descriptive technique that allows researchers to describe a sample  b. A descriptive technique that allows researchers to describe a population  c. An inferential technique that uses the data from a sample to draw inferences about the population d. An inferential technique that uses the data from a population to make predictions about the sample
