Exercise 14.20 page 753 Statistics, Ninth Edition by McClave and Sincinch H a : The distributions of daily accumulated stream flow and precipitation for the two stations differ. H a : The distributions of daily accumulated stream flow and precipitation for the two stations do not differ. Assumptions: The samples were chosen randomly and independently. Accumulation is a continuous variable. Test Statistic: T = T station 1 n Station 1 = 8 and n Station 2 = 9 α = 10 RR: T < 54 or T > 90 Calculations: Station 1 Station 2
