A survey in Men's Health magazine reported that 39% of cardiologists said that they took vitamin E supplements. To see if this is still true, a researcher randomly selected 100 cardiologists and found that 36 said that they took vitamin E supplements. At a = 0.05, test the claim that 39% of the cardiologists took vitamin E supplements. A recent study said that taking too much vitamin E might be harmful. How might this make the results of the previous study invalid? a. State the hypotheses and identify the claim. Identify the statistical test to be used. Find for the critical value(s). b. Sketch a curve with the rejection and non-rejection region. Computer for the test value. c. Make the decision. Interpret the results.
