A health food company wants to determine the best process for blanching dark green vegetable material so it can be added to other food products without losing vitamin A.

a. What are the null and alternative hypotheses (in words, not symbols)?
b. Are the conditions / assumptions for ANOVA met?
c. Calculate the F-statistic.
d. The P-value for this statistic turns out to be < .001. State the conclusion.
