- If the researcher wants to do a 2 tailed hypothesis test based on the data to generalize the relationship, what would the null and alternative hypothesis be? (in words and symbol notation).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.Assuming that the claim falls under the null hypothesis, correctly complete the sentence below. The alternative hypothesis will be the _________ as the claim. same or compliment
