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.

When the null hypothesis is true, the F test statistic is close to .When the null hypothesis is false, the F test statistic is most likely

More than 4.7% of homes have only a landline telephone and no wireless phone. Sample data; a survey by the national center of healthy statistics showed that among 15,944 homes 5.76% had landline phones without wireless phones. express the original claim ina symbolic form. Let the parameter represent a value with respect to homes that have only a landline telephone and no wireless phone identify The null and alternative hypothesis

When the null hypothesis is true, the F test statistic is close to                           ["", "", ""]            . When the null hypothesis is false, the F test statistic is most likely                           ["", ""]

When a hypothesis test is being carried out, there are four different situations that can occur depending on the truthfulness of the null hypothesis. Type I error occurs when the following situation happen The null hypothesis is false, but we mistakenly fail to reject it. The null hypothesis is true, but we mistakenly reject it. The null hypothesis is false, and we reject it. The null hypothesis is true, and we fail to reject it.

Rejecting the null hypothesis when it is true is called a _____ error

In performing a hypothesis test, one should decide whether to reject or not reject the null hypothesis before summarizing the results. True or false. Explain.

Which set of numbers would correspond to a hypothesis test with the greatest power? Cohen's d = 0.6 & n = 500 O Cohen's d = 0.6 & n = 50 O Cohen's d = 0.5 & n = 50 O Cohen's d = 0.5 & n = 500

5. Conclusions True or false: In hypothesis testing, it is never valid to form a conclusion of supporting the null hypothesis.

In hypothesis testing, if the test statistic falls in the critical region then we reject the null hypothesis. a. Trueb. False
