Use technology to help you test the claim about the population mean, u, at the given level of signicance, or, using the given sample statistics. Assume the population is normally distributed. Claim: u > 1280; on = 0.02; o = 201.86. Sample statistics: )_(= 1297.59, n = 250 Identify the null and alternative hypotheses. Choose the correct answer below. 0 A. H0: [121297.59 O 3. Ho: p>1297.59 Ha: p1297.59 O E. H0: p>1280 O F. H0: [151280 Ha: ps1280 Ha: p>1280 Calculate the standardized test statistic. The standardized test statistic is . (Round to two decimal places as needed.) Determine the P-value. P = (Round to three decimal places as needed.) Determine the outcome and conclusion of the test. V H0. At the 2% signicance level, there i 1 enough evidence to V the claim
