Part IV. Hypothesis Testing

14. Your researcher's claim is that the continine level for the ETS group is not equal to zero. Compose a hypothesis test with a level of significance of .05 to test your claim.

Step 1.Determine parameter of interest and compose null and alternative hypotheses.

Step 2.Determine the sample mean, sample standard deviation, and sample size.[Hint:You recorded these previously in this assignment]

Step 3.Determine the likelihood that the population mean is actually not equal to 0 by completing a Hypothesis Test: One Mean in STAT DISK.Use significance of 0.05. Paste results here.Remember that the pulldown menu in Statdisk must match the alternative hypothesis statement.

Conclusion: Since the p-value of 0.6349 is greater than the level of significance (alpha), the null hypothesis is not rejected; therefore, the data supports that the mean systolic pressure level equals 120.

Step 4.State your conclusion. The conclusion statement has a prescribed format: it should include a comparison of the p-value and alpha, whether you reject or support the null hypothesis, and a paraphrase of the hypothesis supported by the data.
