Suppose that we reject a null hypothesis at the 0.001 level of significance. The null hypothesis will definitely also be rejected for all the following a- values except for: A. 0.01 B. 0.0005 C. 0.005 D. 0.05 E. 0.002
A null and alternative hypothesis are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Ho: H 3 7.2 H3: 7.2 What type of test is being conducted in this problem? O A. Right-tailed test O B. Left-tailed test OC. Two-tailed test
A null and alternative hypothesis are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. H0: p ≥ 0.2 Ha: p < 0.2 What type of test is being conducted in this problem?
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) a = 0.01, (b) a= 0.05, and (c) a= 0.10 P= 0.1129 (a) Do you reject or fail to reject H, at the 0.01 level of significance? ur O A. Fail to reject H, because the P-value, 0.1129, is greater than a= 0.01. O B. Reject H, because the P-value, 0.1129 , is greater than a= 0.01. O C. Reject H, because the P-value, 0.1129, is less than a= 0.01. O D. Fail to reject Ho because the P-value, 0.1129, is less than a = 0.01. rai

Suppose there is a claim that a certain population has a mean, H, that is different than 5. You want to test this claim. To do so, you collect a large random sample from the population and perform a hypothesis test at the 0.10 level of significance. To start this test, you write the null hypothesis, Ho, and the alternative hypothesis, H1, as follows. Hg: u= 5 H1: u=5 Suppose you also know the following information. The value of the test statistic based on the sample is 1.506 (rounded to 3 decimal places). The p-value is 0.132 (rounded to 3 decimal places). (a) Complete the steps below for this hypothesis test. Standard Normal Distribution 04 Step 1: Select one-tailed or two-tailed. O One-tailed O Two-tailed 0.3+ Step 2: Enter the test statistic. (Round to 3 decimal places.) 0.2 Step 3: Shade the area represented by the p-value. 0.1+ Step 4: Enter the p-value. (Round to 3 decimal places.) ?

Imagine you are doing a Related-Samples t-test, and you are on Step Three of the hypothesis test. The sample of difference scores that you calculated is -5, -6, +2, -2, 0. What is the correct t-obtained? NOTE: The answer options also show many numbers that you calculate as part of the WORK for getting the t-obtained. VERY IMPORTANT HINT: The SS of these difference scores is 44.80.
Decide whether to reject or fail to reject the null hypothesis. Z (right - tailed test), a = 0.05 Zcomputed = 1.42
Use the six steps of hypothesis testing to answer the following question. Remember to determine if the problem is a Z test or T test as that will influence your critical value. You believe you have discovered a topical solution that heals wounds faster. The average number of days it takes to remove stiches after surgery in all hospital patients is 12. In a sample of 29 patients the average number of days to remove stiches is 10.5 with a std dev. Of 1.2 Did your solution lessen the number of days patients had stiches
