Question

To study the effect of temperature on yield in a chemical process, five batches were produced at each of three temperature levels. The results follow. Temperature 50°C 60°C 70°C 33 34 29 23 35 34 35 38 34 38 27 36 31 31 37.

Answer 1

Step-by-step explanation

Mean = (50+60+70+33+34+29+23+35+34+35+38+27+36+31+31+37)/16 = (603)/16

= 37.69

SS total = 603 - 37.69

= 565.31

SST = (N1-mean)^2 + (Nn -mean)^2 do this for all the values. = 2248.804

SSE = SST - SS = 1683.494

DFT = k-1 = 3-1 = 2

DFE = N-k = 16-2 = 13

MST = SST/DFT = 1124.402

MSE = SSE/DFE =  129.5

Total (corrected) ss =  n-1 = 15
