Question 3 Calculate the single-sided upper bounded 95% confidence interval for the population standard deviation (sigma) given that a sample of size n=6 yields a sample standard deviation of 17.12. Your answer: O sigma < 23.85 O sigma < 65.56 sigma < 14.25 sigma < 59.31 O sigma < 45.66 sigma < 67.88 sigma < 35.77 O sigma < 40.32 O sigma
