- What is your conclusion? Reject the alternative hypothesis and support the claim Fail to reject the null hypothesis and do not support the claim Accept the alternative hypothesis and reject the claim Accept the null hypothesis and support the claim Reject the null hypothesis and support the claimnon directional null and alternative hypothesisConclusions True or false: In hypothesis testing, it is never valid to form a conclusion of supporting the null hypothesis.
- Alternative hypothesis is everything except Represents a theory that has been put forward Frequently “alternative” is actual desired conclusion of the researcher Only considered if H0 is rejected. Opposite of Null Hypothesis.the null and alternative hypothesisWhat is your conclusion? Reject the alternative hypothesis and support the claim Reject the null hypothesis and support the claim Accept the null hypothesis and support the claim Fail to reject the null hypothesis and do not support the claim Accept the alternative hypothesis and reject the claim
- Conclusions True or false: The conclusion of “fail to reject the null hypothesis” has exactly the same meaning as “accept the null hypothesis.”True or false A type I error is defined as rejecting the null hypothesis when the null hypothesis is falseHypotheses and Conclusions Refer to the hypothesis test. a. Identify the null hypothesis and the alternative hypothesis. b. If the P-value for the test Is reported as “less than 0.001,” what should we conclude about the original claim?
- Independent-samples t test: develop a research question that can be addressed with independent-samples t test, and state the null and alternative hypotheses (in words),True or False: A Type I Error is made by failing to reject the null hypothesis when the null hypothesis is actually incorrect.A verdict in a trial has just been announced. The null hypothesis is that the person is innocent. The alternative is guilty. The verdict was a Type II error. What has occurred?
