Test the claim about the population mean, , at the given level of significance using the given sample statistics Claim: # 5000: 0.09; 415. Sample statistics. x 4900, n.35 Ho: #5000 Ha : 2 5000 A. : -6000 E. H0: 5000 Ha: H 5000 B. Ho: -6000 Ha: #5000 ) D. H0'#5000 Ha: 5000 F. Ho:p25000 Ha: #5000 Calculate the standardized test statistic The standardized test statistic is -1.43 (Round to two decimal places as needed.) Determine the critical value(s). Select the correct choice below and fill in the answer box to complete your choic (Round to two decimal places as needed.) O A. The critical value is B. The critical values are

Explanation / Answer
