C. Two tail test, zp= 2.31 and a= 0.05D. Two tail test zp= -1.08 and a= 0.01Determine whether or not to reject the null hypothesis.

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, z = - 1.97, and a = 0.05. p-value = 0.66 (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. Do not reject Ho. since the p-value is less than the significance level a. O 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 greater than or equal to the significance level a. b. One-tail (upper) test, zo = 1.14, and a= 0.10 p-value = 0.003 (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 Ann
