1 points Save QUESTION 2 If we set a = 0.03, we reject the null hypothesis if the probability of our result (or more extreme result), given that the null hypothesis is true, is greater than 0.97 o less than 0.97 greater than 0.03 o less than 0.03
True or false. If the p-value is 6%, then we reject the null hypothesis and accept the alternative hypothesis at a significance level of 10% but not at a significance level of 5%. True or false?
Question 5 2 pts Which of the following statements is true? (a) we reject a null hypothesis if the p-value of the test is smaller than the level of the significance a. (b) we accept a null hypothesis if the p-value of the test is smaller than the level of the significance a. (c) we reject a null hypothesis if the p-value of the test is larger than the level of the significance a. . (a) . (b) . (c)
Briefly discuss the difference between the "Alpha level" (α) and the "p-value". True or False: Reject the null hypothesis when α = 0.042 and p-value = 0.03 True or False: Retain the null hypothesis when α = 0.02 and p-value = 0.010 True or False: Reject the null hypothesis when α = 0.01 and p-value = 0.005 True or False: Retain the null hypothesis when α = 0.001 and p-value = 0.02
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...
Calculate the p-value for the following conditions and determine whether or not to reject the null hypothesis. a) one-tail (upper) test, z Subscript p=2.86, and alpha= 0.10 b) one-tail (lower) test, z Subscript p= -0.74, and alpha= 0.05 c) two-tail test, z Subscript p=-1.93, and alpha=0.05 d) two-tail test, z Subscript p=1.13, and alpha= 0.02 a) p-value= (Round to four decimal places as needed.) Determine whether or not to reject the null hypothesis. Choose the correct answer below. A. Do...
Question 21 (4 points) For a hypothesis test about a population proportion or mean, if the level of significance is less than the p- value, the null hypothesis is rejected. (Ch10) True False Question 22 (4 points) Everything else being constant, increasing the sample size decreases the probability of committing a Type II error. (Ch10) True False The power of a statistical test is the probability of not rejecting the null hypothesis when it is true. (Ch10) True False Question...
Which of the following statements is true? I. If the p-value is 0.01, we reject H0 for any alpha level less than 0.01. II. If we use an alpha level of 0.05, then a p-value of 0.005 is not statistically significant. III. If we use an alpha level of 0.05, then we fail to reject the null hypothesis if the p-value is 0.1. Group of answer choices I only II only III only I and III II and III
question 10-13 Please and Thank you
Question 10 (0.5 points) True or False: The higher the level of significance of a hypothesis test, the stronger the evidence we require to reject the null hypothesis. True False Question 11 (0.5 points) True or False: The purpose of a hypothesis test is to assess the evidence in favour of the null hypothesis True False Question 12 (0.5 points) True or False: The higher the p-value of a hypothesis test, the more evidence...
Which of the following statements is true? I. If the p-value is 0.01, we reject H0 for any alpha level less than 0.01. II. If we use an alpha level of 0.05, then a p-value of 0.005 is not statistically significant. III. If we use an alpha level of 0.05, then we fail to reject the null hypothesis if the p-value is 0.1.
