Probabilistic Analysis of Dissolved Oxygen

18.   The article A Probabilistic Analysis of Dissolved Oxygen—Biochemical Oxygen Demand Relation- ship in Streams (J. Water Resources Control Fed., 1969: 73—90) reports data on the rate of oxygenation in streams at 20°C in a certain region. The sample mean and standard deviation were computed as x =

 

.173 and s = .066, respectively. Based on the accom- panying frequency distribution, can it be concluded that oxygenation rate is a normally distributed vari- able? Use the chi-squared test with a = .05.
