Please use the accompanying Excel data set or accompanying Text file data set when completing the following exercise. An article in the ASCE Journal of Energy Engineering ("Overview of Reservoir Release Improvements at 20 TVA Dams," Vo 1999, pp. 1-17) presents data on dissolved oxygen concentration from streams below 20 dams in the Tennessee Valley A system. The sample mean from the observations is = 3.294 and the sample standard deviation is s = 2.125. Assume approximately normally distributed. Round your answers to 2 decimal places. (a) Calculate the 95% two-sided confidence interval on the mean oxygen concentration. SUSI (b) Calculate the 95% two-sided prediction interval on the dissolved oxygen concentration for the next stream that will E Xn+1 S (c) Find an interval that will contain 95% of the values of the dissolved oxygen concentration with 99% confidence.
