Question I L 0/ 1 pt 10 * 98 Details You wish to test the following claim (H1) at a significance level of a = 0.001. Ho: u = 60.5 H1: u # 60.5 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 348 with a mean of T - 62.1 and a standard deviation of s = 11.7. What is the test statistic for this sample? (Report answer accurate to three decimal places. ) test statistic = Question Help: Video Submit Question Question 2 0/1 pt 9 10 2 98 @ Details You wish to test the following claim (H1) at a significance level of a = 0.001. Ho: ul = 55.1 H1: u > 55.1 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 53 with a mean of a = 56.6 and a standard deviation of s = 15.7. What is the test statistic for this sample?
