3. [4.4/20 points) DETAILS PREVIOUS ANSWERS DEVORESTAT9 11.SE.054. MY NOTES Coal-fired power plants used in the electrical industry have gained increased public attention because of the environmental problems associated with solid wastes generated by large-scale combustion. A study was conducted to analyze the influence of three factors-binder type (A), amount of water (8), and land disposal scenario (C)-that affect certain leaching characteristics of solid wastes from combustion. Each factor was studied at two levels. An unreplicated 23 experiment was run, and a response value EC50 (the effective concentration, in mg/L, that decreases 50% of the light in a luminescence bioassay) was measured for each combination of factor levels. The experimental data is given in the following table: Factor B Run А с -1 1 2 3 -1 -1 -1 1 Response EC50 23,200 41,000 71,100 76,000 37.000 33,200 17.000 16,500 4 -1 1 -1 1 -1 1 -1 1 1 -1 1 5 6 7 - 1 1 1 1 1 AC'S = 0 B0g = 0 MS The hypotheses are as follows: Hoa: alla's = 0 Hogi all B,'s = 0 Hoci all's = 0 Hay at least one a, # 0 Hagi at least one B, * 0 Haci at least one *0 8 Hotgi all y, ABS = 0 #các all yº Hoecall H24B: at least one Po 48 = 0 Haci at least one y KC = 0 Haec at least one BC0 Carry out an appropriate ANOVA, and state your conclusions.
