A survey in Mens health magazine reported that 39% of cardiologists said that they took vitamin
E supplements. To see if this is true, a researcher randomly selected 100 cardiologists and found
that 36 said they take vitamin E supplements. At alpha = 0.05, test the claim that 39% of the
cardiologists took vitamin E supplements.
What parameter are you testing (mean, proportion, variance)?
Is this a one tail or two tail test?
State the null and alternative hypothesis.
Draw the curve and identify your critical values.
Convert your sample statistic into a test statistic and plot it on your curve.
Do you accept or reject the null hypothesis?
Is there a chance for a type I or type II error?.
This PowerPoint helps students to consider the concept of infinity.
