You wish to test the following claim ( H a ) at a significance level of α = 0.002 . H o : μ = 58.1 H a : μ > 58.1 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 516 with mean ¯ x = 59.8 and a standard deviation of s = 13.5 . What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = Incorrect What is the p-value for this sample? (Report answer accurate to four decimal places.)
