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…

Write down the sample space for the outcome when flipping a fair coin three times... What is the probability of exactly 2 Heads? What is the probability of at least 3 tails A survey of 451 Salinas residents showed 389 voted in a recent election. When making a selection from the 451 surveyed, what is the probability the person voted in a recent election? When making a selection from the 451 surveyed, what is the probability the person did not vote in a recent election?
