Problem
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 $88 \%$ 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 a statement of equality, it represents the hypothesis. (a) How should you interpret a decision that rejects the null hypothesis? There is evidence to the claim that at least $88 \%$ 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 the claim that at least $88 \%$ of people had at least one health care visit in the past year.
Solution
Step 1 ：The claim represents the alternative hypothesis.
Step 2 ：If the null hypothesis is rejected, it means that there is statistical evidence to support the claim that at least 88% of people had at least one health care visit in the past year.
Step 3 ：If the null hypothesis is not rejected, it means that there is not enough statistical evidence to support the claim that at least 88% of people had at least one health care visit in the past year.
