3. Example 10.5.1 : Four tropical feedstuffs were each fed to a lot of 5 baby chicks (9). The gains in weight where a. Looking at your data does it look like each mean is more or less the same? b. Preform an ANOVA c. State your conclusion d. Does this justify an SR5 or a stratied study into the future 4. Verify that if you combine lots 1&2 and lots 3&4 you are preforming a t-test 5. Verify that for df1 = 1 and df2 = 20 the 5% and 1% signicance levels from the F table are the same as those from the t-table 6. Repeat problem 3 but generate your own random data, in this case using the same mean for each lot. Verify through Monte Carlo methods that you end up falsely rejecting the null hypothesis at the rate your F-table suggests you will
