A study about the effect of different type of vitamin and food on chicken growth (weight in
grams) has been investigated. The incomplete two-way ANOVA output is given as:
SS
i.
ii.
iii.
iv.
Source of Variation
Type of vitamin
Type of food
Interaction

State the experimental units in this experiment.
Calculate D, E, F, G. You must show the calculation process.
P-value
5.86 X 10-5
0.002
0.676
At a 5% significance level, what can you conclude from the ANOVA output? Support
your answer. Conclude in the context of the above scenario.
Comment whether this statement is correct or incorrect and state your reason: "The
main effect refers to the effect of a factor on two independent variables."
