Alternative medicine A nationwide random survey of 1500 adults asked about attitudes toward alternative medicine such as acupuncture, massage therapy, and herbal therapy. Among the respondents, 660 said they would use alternative medicine if traditional medicine was not producing the results they wanted. Do these data provide good evidence that more than 1/3 of all adults would use alternative medicine if traditional medicine did not produce the results they wanted? (a) State the hypotheses to be tested. (b) If your null hypothesis is true, what is the sampling distribution of the sample proportion p^? Sketch this distribution. (c) Mark the actual value of p^ on the curve. Does it appear surprising enough to give good evidence against the null hypothesis? (d) Carry out the signifi cance test called for in detail. Show the steps of the inference procedure (hypotheses, sampling distribution, data, P-value, conclusion) clearly
