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 less than 13​% of people had no health care visits in the past year.       Does the claim represent the null hypothesis or the alternative​ hypothesis?   Since the claim ▼   does not contain contains a statement of​ equality, it represents the ▼   alternative null hypothesis. ​(a) How should you interpret a decision that rejects the null​ hypothesis?   There is ▼   sufficient insufficient evidence to ▼   support reject the claim that less than 13​% of people had no health care visits in the past year. ​(b) How should you interpret a decision that fails to reject the null​ hypothesis?   There is ▼   insufficient sufficient evidence to ▼   support reject the claim that less than 13​% of people had no health care visits in the past year.
