Test the claim about the population mean $?$ at the level of significance $?$. Assume the population is normally distributed. Claim: $??1473;?=0.06;?=27$. Sample statistics: $x?=1464,n=27$ Identify the null and alternative hypotheses. Choose the correct answer. A. $H_{0}:?>1464H_{a}:??1464?$ C. $H_{0}:?<1464H_{a}:??1464?$ E. $H_{0}:??1473H_{a}:?<1473?$ B. $B.H_{0}:??1464H_{a}:?<1464?D.H_{0}:?>1473H_{a}:??1473?F.H_{0}:?<1473H_{a}:??1473?$ Calculate the standardized test statistic. The standardized test statistic is (Round to two decimal places as needed.)
