2. A study was conducted to see if there were differences in gain in baby chicks fed four different feeds. Two of the feeds (A and B) contained standard small particle sizes, while feeds C and D contained large particle sizes. Feeds A and C were from Manufacturer X, while Feeds B and D were from Manufacturer Y. Each feed was randomly assigned to five lots of chicks and the total gain of each lot over 2 weeks was recorded. The researcher was interested in the following comparisons 1) Differences between Small vs Large particle size on gain 2) Differences in two small particle size on gain 3) Differences in gain between feeds produced by Manufacturers X vs Y. 2) Fill in the table testing the null hypotheses for the listed one-degree of freedom contrasts (MSE=5.65).
