Treatment of wastewater is important to reduce the concentration of undesirable pollutants. In order to compare two methods of water treatment, five specimens of waste water are treated using treatment 1 (T1), & another five specimens of waste water are treated using treatment 2 (T2). The belief is that the mean concentration is less for T2 compared to T1. Assume all normal distribution conditions. The benzene concentrations, in units of mg / L, for each specimen are as follows: T1: 7.8 7.6 5.6 6.8 6.4 T2: 7.3 6.5 4.1 5.9 4.7 Write out the alternative hypothesis, & the test statistic (rounded to 4 decimal places), the order being first T1 & then T2. NOTE: wy is the mean / average of T1, My _ 2) is the mean of the paired observation in the order first T1 & then T2, etc. OA. Hy > H2, & 1.6096 O B. None of the other answers are correct. O C.
