Question 19 You wish to test the following claim (H1 ) at a significance level of a = 0.10. Ho: u = 70.9 H1: u # 70.9 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 11 with a mean of M = 75.8 and a standard deviation of SD = 20.5. When finding the critical value and test statistic, which distribution would we be using? O Normal distribution (invNorm for critical value) OT distribution (invT for critical value) Ox distribution (invx for critical value) OF distribution (invF for critical value)
