a) 99% two-sided confidence interval on o n = 10 s = 1.913 x00s 9 = 23.59 and xo 9959 = 1.73 9(1.913)? so? 9(1.913)? 23.59 1.73 1.396 s o? s 19.038 b) 99% lower confidence bound for o For a = 0.01 and n=10, x- - Xo019 =21.67 9(1.913)? so? 21.67 1.5199 so? c) 90% lower confidence bound for o? For a = 0.1 and n = 10, Xan-1 9(1.913) Xó19 =14.68 = so? 14.68 2.2436 so? 1.498 s o d) The lower confidence bound of the 99% two-sided interval is less than the one-sided interval. The lower confidence bound for o is in part (c) is greater because the confidence is lower.
