α is the probability of a Type I error, which occurs when we accept the alternative H1 when the null hypothesis Ho is true. True False A Type II error occurs when when a false null hypothesis is rejected. True False If a null hypothesis is rejected at the 5% significance level but not at the 1% significance level, then the p-value of the test is less than 1%. True False The power of a test is the probability of...
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)
On the basis of sample information, we either "accept the null hypothesis" or "reject the null hypothesis." True O False
6 – Test Statistic LEARNING OBJECTIVE: Determine whether to reject a null hypothesis from a given p-value and significance level. BOOO > Select the correct statement. a.) Given a p-value of 0.01, and a significance level of 5%, you should reject the null hypothesis. b.) Given a p-value of 0.08, and a significance level of 2%, you should reject the null hypothesis. c.) Given a p-value of 0.06, and a significance level of 5%, you should reject the null hypothesis. d.) Given a p-value of...
8. A very small p-value indicates that: a. we should accept the alternative hypothesis. b. we should reject the null hypothesis and the alternative hypothesis. c. we should reject the null hypothesis. d. we should not reject the null hypothesis.
Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. A test of sobriety involves measuring the subject's motor skills. A study of n = 20 randomly selected sober subjects take the test and produce a mean score of X = 41.0, and we know that o = 3.7. At the 0.01 level of significance, test the claim that the true mean score for all sober subjects is...
The power of a test is the probability that we _____ the null hypothesis when the alternative hypothesis is _____. ? A) reject, true B) accept, true C) accept, false D) reject, false (IT IS NOT D)
If the p-value = 0.4567, then which of the following is true. A. We fail to reject Ho at a significance level = .05 B. We fail to reject Ho at a significance level = .10 C. We fail to reject Ho at a significance level = .01 D. All of these answers are correct When choosing between a biased but very efficient estimator and an unbiased but very inefficient estimator, we should choose the one with the minimum Mean...
Please explain it with proper reasoning. 3. The following statements are very important. Give them some careful thought and discuss them (a) When we fail to reject the null hypothesis, we do not claim that it is abso- lutely true. We simply claim that at the given level of significance, the data were not sufficient to reject the null hypothesis (b) When we accept the alternate hypothesis, we do not claim that the null hypothesis is absolutely false. We do...
