Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis or (b) fails to reject the null hypothesis? A researcher claims that at least 82% of people had at least one health care visit in the past year. Does the claim represent the null hypothesis or the alternative hypothesis? Since the claim does not contain a statement of equality, it represents the hypothesis. (a) How should you interpret a decision that rejects the null hypothesis? There is evidence to V the claim that at least 82% of people had at least one health care visit in the past year. (b) How should you interpret a decision that fails to reject the null hypothesis? There is evidence to V the claim that at least 82% of people had at least one health care visit in the past year.
