Define (a) hypothesis-testing procedure, (b) 0.05 significance level, and (c) two-tailed test. (a) Choose the correct answer below. O A. Start the hypothesis-testing procedure by restating the question as a research hypothesis and a null hypothesis pertaining to the populations. Then determine the characteristics of the normal distribution and determine the cutoff sample score of the said distribution at which the null hypothesis should be rejected. Next determine the sample's score on the normal distribution and decide whether to reject the null hypothesis. O B. Start the hypothesis-testing procedure by restating the question as a research hypothesis and a null hypothesis pertaining to the populations. Then determine the characteristics of the comparison distribution and determine the cutoff sample score of the said distribution at which the null hypothesis should be rejected. Next determine the sample's score on the comparison distribution and decide whether to reject the null hypothesis. O C. Start the hypothesis-testing procedure by restating the question as a research hypothesis and a null hypothesis pertaining to the populations. Then determine the characteristics of the comparison distribution and determine the cutoff sample score of the said distribution at which the research hypothesis should be rejected. Next determine the sample's score on the comparison distribution and decide whether to reject the research hypothesis. (b) Choose the correct answer below. O A. A 0.05 significance level is the cutoff on the comparison distribution with a probability of 5% that a score will be at least that extreme if the null hypothesis were true. This probability is usually written as p 0.05. O D. A 0.05 significance level is the cutoff on the comparison distribution with a probability of 95% that a score will be at least that extreme if the null hypothesis were true. This probability is usually written as p 0.05. O D. A0115 signicance level is the cutoff on the comparison distribution with a probability of 95% that a score will be at least that extreme ifthe null hypothesis were the. This probability is usually written as p
