Transcribed Image Text:
A farm animal feed company is developing a new line of pig feed. It has created four different formulations and is interested in knowing which pig feed is most
efficient at fattening them up. 12 pigs from 3 different litters (A,B and C) were selected, 3 pigs from each litter were exclusively fed one type of feed (1, 2, 3 or 4).
After 2 years each pig was weighed. Litters were used as blocking effect to control for the possiblility of genetics playing a role in size. The total standard deviation
of dataset was 1.64. Interactions were found to be not significant. A summary of the cell and column means is given below.
