A hypothesis test uses a significance level of 5%. The Power of the Test is 0.90. Which of these statements are True? I. The Probability of incorrectly rejecting the Null is 0.05. II. The probability of incorrectly accepting the Null is 0.10. A. I only. B. II only. C. I. & II. D. None of them. А. А В. В С. С D. D
In a given hypothesis test, the null hypothesis cannot be rejected at the 0.005 and the 0.01 level of significance, but can be rejected at the 0.03 level. The most accurate statement about the p- value for this test is: O A. p-value 0.03

Suppose 220 subjects are treated with a drug that is used to treat pain and 55 of them developed nausea. Use a 0.10 significance level to test the claim that more than 20% of users develop nausea. Identify the null and alternative hypotheses for this test. Choose the correct answer below. А. Hо: р30.20 H1:p>0.20 В. Но: р> 0.20 H1:p= 0.20 С. Но: р3D0.20 H4: p<0.20 D. Ho: p= 0.20 H4:p#0.20 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is. (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. A. Reject Ho: There is not sufficient evidence to warrant support of the claim that more than 20% of users develop nausea. B. Reject Ho. There is sufficient evidence to warrant support of the claim that more than 20% of users develop nausea. C. Fail to reject Ho. There is not…
what is the correct choice
7. The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) α = 0.01, (b) x = 0.05, and (c) α = 0.10. P = 0.1176 (a) Do you reject or fail to reject Hå at the 0.01 level of significance? O A. Fail to reject Ho because the P-value, 0.1176, is greater than α = 0.01. Reject Hå because the P-value, 0.1176, is greater than α = 0.01. O B. O C. Fail to reject Ho because the P-value, 0.1176, is less than α = 0.01. O D. Reject Ho because the P-value, 0.1176, is less than α = = 0.01. (b) Do you reject or fail to reject Ho at the 0.05 level of significance? O A. Fail to reject Ho because the P-value, 0.1176, is less than α = 0.05. B. Fail to reject Ho because the P-value, 0.1176, is greater than α = 0.05. O C. Reject Ho because the P-value, 0.1176, is greater than α = = 0.05. D. Reject Ho because the P-value, 0.1176, is less than α = = 0.05. (c) Do you reject or fail to reject Ho at the 0.10 level of significance? O A. Reject…

Only about 14% of all people can wiggle their ears. Is this percent lower for millionaires? Of the 400 millionaires surveyed, 40 could wiggle their ears. What can be concluded at the a = 0.10 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Но: ? Select an answer V (please enter a decimal) H1: ? v Select an answer V (Please enter a decimal) c. The test statistic ? v (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 3 decimal places.) e. The p-value is ? v a f. Based on this, we should Select an answer g. Thus, the final conclusion is that ... the null hypothesis. O The data suggest the population proportion is not significantly lower than 14% at a = 0.10, so there is statistically insignificant evidence to conclude that the population proportion of millionaires who can wiggle their ears is lower than 14%. O The data suggest the populaton proportion is significantly lower…
