A company that sells honey wishes to find out if the strain of bee they use (strain 1) is the most productive bee available. To study the question the four available strains are tested at their research farm to see how much honey is produced by each type of bee. Test hives are set up and the number of ounces of honey each hive produces is recorded and given below.
a. Are any a priori comparisons appropriate and if so which ones?
b. Using a = .05 1 tail is there a difference between strain 1 and strain 2 using planned comparisons?
c. Using a = 0.05 and the HSD test, which strains are different in the amount of honey they produce?
d. Same as part c, using the Scheffé test.
