17 The nicotine patch is an FDA-approved medicine that can help people quit smoking. To test the effectiveness of the nicotine patches, a researcher selected a random sample of 400 adults who used patches. He wants to test whether less than 75% of them quit smoking. The appropriate null and alternative hypotheses are H0: p ≤ 0.75 vs H1: p > 0.75 H0: p > 0.75 vs H1: p ≤ 0.75 H0: p = 0.75 vs H1: p ≠ 0.75 H0: p ≥ 0.75 vs H1: p < 0.75

In hypothesis testing the statistical conclusion is either to reject or not to reject the null hypothesis based on the sample data. Which of the following statements is true? The conclusion will always reject a false null hypothesis. The conclusion is always subject to error because it is based on sample data. The conclusion will never reject a true null hypothesis.

A student compared organic food prices at Grocery 1 and Grocery 2. The same items were priced at each store. The first three items are shown in the accompanying Figure A. Choose the correct accompanying output (B or C) for the appropriate test, explaining why you chose that output. Then test the hypothesis that the population means are not equal using a significance level of 0.05. Assume i Figure A and Outputs Click the icon to view Figure A and the outputs. Which is the correct output (B or C) for the appropriate test? Explain. (Figure A) Food Grocery 1 0.89 Grocery 2 0.99 A. Output B is appropriate because the data are paired samples.
