Calculate the p-value for the following conditions and determine whether or not to reject the null hypothesis. Complete parts a through d. a. One-tail (lower) test, Zp = - 1.12, and a = 0.05. p-value = (Round to four decimal places as needed.) Determine whether or not to reject the null hypothesis. Choose the correct answer below. O A. Reject Ho, since the p-value is greater than or equal to the significance level a. O B. Reject Ho, since the p-value is less than the significance level a. O C. Do not reject Ho, since the p-value is greater than or equal to the significance level a. O D. Do not reject Ho, since the p-value is less than the significance level a. b. One-tail (upper) test, Zp = 1.01, and a = 0.10. p-value = (Round to four decimal places as needed.) Determine whether or not to reject the null hypothesis. Choose the correct answer below. O A. Do not reject Ho, since the p-value is greater than or equal to the significance level a. O B. Reject Ho, since the p-value is greater than or equal to the significance level a. C. Reject Ho, since the p-value is less than the significance level a. O D. Do not reject Ho, since the p-value is less than the significance level a. c. Two-tail test, Zp =2.17, and a = 0.05. p-value = (Round to four decimal places as needed.) Determine whether or not to reject the null hypothesis. Choose the correct answer below. O A. Reject Ho, since the p-value is less than the significance level a. O B. Reject Ho, since the p-value is greater than or equal to the significance level a. O C.
