\f7. Consider a null hypothesis stating that the population mean is equal to 52, with the research hypothesis that the population mean isn't equal to 52. Assume you've collected 38 sample data from which we computed a sample mean of 53.67 and a sample standard deviation of 3.84. Further assume the sample data appear approximately normal. What's the p-value you would report for this test? O A. 0.0074 O B. 0.0084 0 C. 0.0041 0 D. 0.0025 4. What's the rejection region for a two-tailed test when a = 0.05? O A. z > 2.575 O B. z > 1.645 O C. z > 1.96 O D. | z > 2.5756. Which of the following statements about p-value testing is true? O A. P-value testing applies only to one-tail tests. O B. The p represents sample proportion. O C. P-value testing uses a predetermined level of significance. O D. The p-value is the lowest significance level at which you should reject Ho
