Calculate the single-sided upper bounded 99% confidence interval for the population standard deviation (sigma) given that a sample of size n=10 yields a sample standard deviation of 16.62. Your answer: O sigma 33.22 O sigma 31.27 sigma 64.00 O sigma 6.41 O sigma 2.02 O sigma -40.41 sigma 38.17 O sigma 43.21 O sigma 34.51 O sigma 60.81
