Calculate the single-sided upper bounded 99% confidence interval for the population mean (mu) given that a sample of size n=9 yields a sample mean of 3.88 and a sample standard deviation of 1.83. Your answer: O mu < 5.04 mu < 5.65 mu < 5.23 mu < 5.54 mu < 6.87 mu < 5.09 mu < 5.05 mu < 7.05 mu < 6.91 mu < 4.72
