Consider the following hypothesis test: A sample of 140 is used and the population standard deviation is 13. Compute the p-value and state your conclusion for each of the following sample results. 0.05. Round z value to two decimal places and p-value to four decimal places. If your answer is zero, enter "0". Enter negative value as negative Use a = number. a. I = 83 z value p-value conclusion b. x = 81 z value p-value conclusion c. = 78.5 z value p-value conclusion d. x = 86 z-value p-value conclusion Select your answer - Ho - Select your answer - Ho Select your answer - Ho : > 84 Ha: < 84 - Select your answer - Ho
