- Determine the second step of hypothesis testing, and explain the procedure and logic of this step. Choose the correct answer below. A. The second step is to figure out the probability of getting a particular result if the research hypothesis is true. In this process, one wants to determine the probability of getting a sample score as extreme as the one found if the sample were from a population with a distribution corresponding to the research hypothesis being true. B. The second step is to determine if the test should use a directional hypothesis or a nondirectional hypothesis. Once this is determined, the correct cutoff sample scores can be obtained. C. The second step is to determine the characteristics of the comparison distribution. The overall logic of hypothesis testing involves figuring out the probability of getting a particular result if the null hypothesis is true. In this process, one wants to determine the probability of getting a sample score as…arrow_forwardDo a hypothesis for the following, make sure to include and label all five steps: Test the claim that tutoring influences a student’s test scores.

- In a study of 819 randomly selected medical malpractice lawsuits, it was found that 473 of them were dropped or dismissed. Use a 0.01 significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed. Which of the following is the hypothesis test to be conducted? ОА.

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= 0.0158 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? O A. Reject H, because the P-value, 0.0158, is greater than a = 0.01. O B. Fail to reject H, because the P-value, 0.0158, is greater than a = 0.01. O C. Fail to reject Ho because the P-value, 0.0158, is less than a = 0.01. O D. Reject Ho because the P-value, 0.0158, is less than g = 0.01. (b) Do you reject or fail to reject Ho at the 0.05 level of significance?arrow_forward
