You wish to test the following claim at a significance level of 0.002. Ho: u = 86.2 H1: u

You wish to test the following claim at a significance level of 0.002. = 86.2 < 86.2 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size 119 with a mean of 84.5 and a standard deviation of 15.4. What is the critical value for this test? (Report answer accurate to 3 decimal places.) -2936 What is the test statistic for this sample? (Report answer accurate to 3 decimal places.) 0885 This test statistic leads to a decision to O reject the null O accept the null O fail to reject the null As such, the final conclusion is that O there is sufficient evidence to conclude that the population mean is equal to 86.2. O there is not sufficient evidence to conclude that the population mean is equal to 86.2. O there is sufficient evidence to conclude that the population mean is less than 86.2. O there is not sufficient evidence to conclude that the population mean is less than 86.2.
