Null Hypothesis Conclusion 07 Use the given information to state the conclusion about the null hypothesis HO Assume a significance level of 0.01. Originalbec claim: The percentage of settled medical malpractice suits is. at least 50% The hypothesis test results in a P-value of 0.012. Answer 1. Reject Ho because the P-value is greater than alpha. 2.Fail to reject reject Ho because the P-value is less than alpha. 3. Fail to reject reject Ho because the P-value is greater than...

You conduct a hypothesis test for the population mean. After you calculate the t test statistic, you find that your p-value = 0.04. Using alpha (a) = 0.01 level of significance, what is your decision regarding the null hypothesis? (either reject Ho and accept Ha, or fail to reject Ho)

Assume for a given study that the null hypothesis asserts the expected value of a phenomenon is 10. A research study results in a 95 percent confidence interval reported as [7.142, 9.865]. What decision should be made based on this confidence interval (for a two-tailed test with an alpha level of 0.05 or 5%)? Group of answer choices Fail to reject the null hypothesis Fail to reject the alternative hypothesis Reject the null hypothesis Perform a hypothesis test before making...

Given the following information, would your decision be to reject or fail to reject the null hypothesis? In addition, briefly explain what your decision means for the research problem. Keep in mind that the level of significance is .05. The null hypothesis that there is no relationship between the amount of coffee consumed and a student’s GPA (p = .05).

The Shapiro-Wilk test is specifically designed to test the hypothesis. H0: Y has a normal distribution versus H1: Y does not have a normal distribution. Jessie obtains a normal sample of size n = 400 for Y = smoothness of a 3-D printed surface. Her choice for alpha is 0.025 and the Shapiro-Wilk test gives her p-value = 0.023. Which (one) of the following should she do? 1. Reject the alternative hypothesis because it has only a 2.3% chance of...

1) Select the answer with the correct choices for scenarios A and B regarding the null hypothesis (H0). Scenario A - If we have chosen an alpha (α) of .05 for a two tailed test and our Z obtained is 1.70, what decision do we make regarding the null hypothesis (H0)? Scenario B - If we have chosen an alpha (α) of .01 for a left tailed test and our Z obtained is -2.24, what decision do we make regarding...
