A sample mean, sample size, and population standard deviation are provided below. Use the one-mean z-test to perform the required hypothesis test at the 10% significance level. x = 28, n=30, a =5, Ho u = 29, Ha u#29 The test statistic is z= -1.1. (Round to two decimal places as needed.) Identify the critical value(s). Select the correct choice below and fill in the answer box within your choice. (Round to three decimal places as needed.) OA. The critical value is z = OB. The critical value is -Za OC. The critical values are ±2a/2 = ±
