15. An alpha of 0.01 means that a decision to the null hypothesis has a in...
Regarding the null hypothesis, what would be the decision made for a t-test of ‘no difference’ that returns a p-value of 0.000? Assume an alpha value of 0.05. A). Fail to reject the null hypothesis. B) Reject the null hypothesis.
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)
Step 2 of 2: Make a decision. Reject the null
hypothesis for fail to reject the null hypothesis
Given the following information: nj = 31,5 = 31.731, n2 = 19. s = 58.94. He: 0 < 62. a = 0.01 Copy Data Step 1 of 2: Determine the critical value(s) of the test statistic. If the test is two-tailed, separate the values with a comma. Round your answer(s) to four decimal places.
Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test, i.e., describe the values of the test statistic that would result in rejection of the null hypothesis. We wish o compare he means of two populations using paired observations. Suppose hat d: 3 12 sd 2. and n : 8 and that you wish to est e h pothesis below at he 1 % level of signiticance hat decision le ou d ou u O A....
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...
Question 15 This distribution is used for confidence intervals with large samples. χ² Z T F Question 16 You can reject a null hypothesis at the .01 alpha level and fail to reject it at the .05 alpha level. True False Question 17 When nominal data are categorized, no overlapping can occur. We refer to these categories as being what? fill in the blank Question 18 Explain the difference between interval and ratio level data in your own words. Provide...
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...
Explain what the below mathematical information means in written paragraph or two : NULL HYPOTHESIS H0: ALTERNATIVE HYPOTHESIS Ha: Not all means are equal. alpha=0.05 Test statistic F=16.821 P value=0.000 Since P value SMALLER than the level of significance therefore SIGNIFICANT. Decision: DO NOT REJECT H0. Conclusion: There is sufficient evidence to conclude that the marks obtained by the Brothers are different.
