Test the claim about the population mean mu at the level of significance alpha. Assume the population is normally distributed. Claim: mugreater than or equals1475; alphaequals0.05; sigmaequals30. Sample statistics: x overbarequals1467, nequals29 Question content area bottom Part 1 Identify the null and alternative hypotheses. Choose the correct answer. A. Upper H 0: mugreater than1467 Upper H Subscript a: muless than or equals1467 B. Upper H 0: mugreater than or equals1475 Upper H Subscript a: muless than1475 Your answer is correct.C. Upper H 0: muless than1467 Upper H Subscript a: mugreater than or equals1467 D. Upper H 0: muless than1475 Upper H Subscript a: mugreater than or equals1475 E. Upper H 0: mugreater than1475 Upper H Subscript a: muless than or equals1475 F. Upper H 0: mugreater than or equals1467 Upper H Subscript a: muless than1467 Part 2 Calculate the standardized test statistic. The standardized test statistic is negative 1.44.
