Question

Penicillin is produced through a fermentation process Investigators want to compare the yield from two different production methods They will be testing across several days and each day they start a new fermentation process Under v; hat situations might the investigators want to consider blocking on the day'? For the testing difference between the two production methods how many numerator degrees of freedom would there be for the F-test? For testing the day (block) effect, the investigators found a p-value of p=0.093 What can they conclude? There is a statistically significant association of block with production yield There is no association of block and production yield Unable to claim a statistically significant association between block and production yield Blocking had no statistically significant association with production method If there are a sufficient number of block then the investigators could also test for an interaction term for production method and block. What would be including the interaction in the model give the invest gators that they would not have gotten in the

Explanation / Answer

A-1)

They might want to consider the following things:-

a) Water needed.

b) Other ingredients and mixture required for fermentation.

c) Other resources, For ex:- Land/industry, oxygen level etc needed for fermentation.

A-2)

Degrees of Freedom would be 1

A-3)

c. Unable to claim a statistically, significant association between block and production yield.

A-4)

Interaction takes place when the independent variables are not independent and have an effect on the dependent variable when they have an interaction. Thus, including IVs interaction would bring to them the effect of interaction which the above would not have brought them.
