A 2 times 2 factorial study was done to investigate the effect of drink fortification on Y=cellular retention of iron. The 2 factors were iron fortification (high and low) and zinc fortification (high and low). There were 8 EU per treatment. A two-way ANOVA as used to analyze the data and produced this partial ANOVA table (a=0.05): Complete the table and provide results and inference Construct a line graph of the treatment means

Solution

Source            df                   SS                MS         Fs =MS/MSE       P-value

iron levels          1                   4.4023          4.4023           1518.034          1.0000

Zinc levels      1                   0.0109         0.0109            3.758621          0.9316

Interaction within group          7                  1.655            0.2364           81.51724          1.0000

Error                                  27-7-1-1=18     0.0528          0.0029                        

Total               2*2*7-1=27      6.1210

In all case the p- value is greater than 0.05 in that case we accept the null hypothesis and we say that there is main and interatcition effect presents between the experimrnt units.
