Question 21 You wish to test the following claim (HI) at a significance level of a = 0.05. = 85.3 < 85.3 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 682 with a mean of M 83.5 and a standard deviation of SD = 15.8. When finding the critical value and test statistic, which distribution would we be using?
