If the p value for a hypothesis test is 0.0271, which would be a correct decision? Do not reject the null hypothesis when alpha is 0.10. Do not reject the null hypothesis when alpha is 0.05. Reject the null hypothesis when alpha is 0.025. Reject the null hypothesis when alpha is 0.10. none of the above
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...
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)
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...
, in a (two-tail) hypothesis test, the p-value is 0.0758, what is your statistical decision if you test the null hypothesis at the 0.05 level of significance? Choose the correct answer below? Please Explain why because I am very confused with this chapter. Thanks! A. Since the p-value is less than alpha comma do not reject Upper H 0 . B. Since the p-value is less than alpha comma reject Upper H 0 . C. Since the p-value is greater...
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.
One tailed t-test O One tailed z-test Question 14 4 pts Which of the following statements most adequately summarizes the conclusion statement resulting from a p-value of 0.03? O We fail to reject the null hypothesis at the alpha level 0.1 We reject the null hypothesis at the alpha level of 0.05 We reject the null hypothesis at the alpha level of 0.01 O We fail to reject the null hypothesis at the alpha level 0.05 Question 15 4 pts
Identify the null hypothesis. alternative hypothesis, test statistic, decision about the null hypothesis and final conclusion that addresses the original claim Various temperature measurements are recorded at different times for a particular city. The mean of 20 degrees is obtained for 60 temperatures on 60 different days. Assuming that the population standard deviation is 1.5 degrees, test the claim that the population mean is 22 degrees. Use a 0.05 significance level Hou = 22; H1 is u# 22 Test statistic:...
A test of hypotheses for one proportion has the following Null Hypothesis: pi = 0.33, and uses 0.10 for the level of significance. a. If the calculated value for the associated test statistic equals -1.71, determine the p-VALUE for the test 0.0436 0.4564 0.2262 0.0872 b. If you compare the p-VALUE from Part a to the level of significance, what decision do you make? Fail to Reject Null Reject Alternative Reject Null Fail to Reject Alternative
If, in a one-tail hypothesis test, the p-value=0.5122 what is the statistical decision if the null hypothesis is tested at the 0.07 level of significance? What is the statistical decision? A) Since the p-value is less than α=0.07, do not reject H0. B) Since the p-value is greater than or equal to α=0.07, do not reject H0. C)Since the p-value is greater than or equal to α=0.07, reject H0. D) Since the p-value is less than α=0.07, reject H 0...
