Question
You wish to test the following claim (H) at a significance level of a = 0.001. Ho: μ = 88.1 88.1 Ha: You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 19 with a mean of M = 80.2 and a standard deviation of SD = 18.2. What is the critical value for this test? (Report answer accurate to three decimal places.) critical value = ± What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = The test statistic is... O in the critical region O not in the critical region This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null
