Test the claim about the population mean at the level of significance. Assume the population is normally distributed. Claim: H < 5115; α = 0.05. Sample statistics: x = 5217, n = 55. What are the null and alternative hypotheses? Ho: μ ≥ 5115 Ha: μ < 5115 (Type integers or decimals. Do not round.) Find the standardized test statistic. 0.05 (Round to two decimal places as needed.)
