Use technology to help you test the claim about the population mean, μ, at the given level of significance, a, using the given sample statistics. Assume the population is normally distributed. Claim: >1270; a 0.03; o 210.16. Sample statistics: x=1298.03, n=300 Identify the null and alternative hypotheses. Choose the correct answer below. OA. Ho ≥1270 Ha <1270 OC. Ho H≥1298.03 Ha <1298.03 E. Ho s 1270 Ha > 1270 Calculate the standardized test statistic. The standardized test statistic is ☐ (Round to two decimal places as needed.) R OB. Ho H>1270 Ha: ≤1270 OD. Ho: >1298.03 Ha: ≤1298.03 OF. Hos 1298.03 H₂: >1298.03
