- 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…An opinion poll asked a random sample of high school couples in the United States whether they believe they will marry their high school sweetheart. A researcher believes more than 25% of high school couples believe they will marry. Which null and alternative hypotheses should be used to test this claim? O Ho: p = 0.25, Ha: p > 0.25 O Ho: p = 0.25, Ha: p 0.25, Ha: p = 0.25 O Ho: P = 0.25, Ha: p > 0.256.
- In a hypothesis test, a Type II error occurs when: a false null hypothesis is rejected O a true null hypothesis is not rejected O a false null hypothesis is not rejected O a true null hypothesis is rejectedDetermine 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 more than 85% 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 contains a statement of equality, it represents the ▼ null alternative hypothesis. (a) How should you interpret a decision that rejects the null hypothesis? There is ▼ sufficient insufficient evidence to ▼ support reject the claim that more than 85% 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 ▼ insufficient sufficient evidence to ▼ support…A researcher claims that more than 60% of the registered voters favor President Trump's tax cut proposal.

- 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 87% 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 ▼ contains does not contain 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 ▼ reject support the claim that at least 87% 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 ▼ insufficient sufficient evidence to ▼ reject support…A hypothesis test is to be performed. Describe the two possible outcomes of the test using the context of the given situation.Last month the average waiting time at a bank was 8.4 minutes. The manager has installed a new computer system and claims that people will no longer have to wait as long. The hypotheses are as follows:Null hypothesis: average waiting time = 8.4 minutes Alternative hypothesis: average waiting time < 8.4 minutes Rejecting the null hypothesis means there is insufficient evidence that the mean waiting time is equal to 8.4 minutes. Accepting the null hypothesis means there is evidence to conclude that the mean waiting time is equal to 8.4 minutes. Rejecting the null hypothesis means there is evidence that the mean waiting time is not equal to 8.4 minutes. Failing to reject the null hypothesis means there is insufficient evidence to conclude that the mean waiting time is less than 8.4 minutes. Rejecting the null hypothesis means there is…
