Exercise 4.3dogsTwo different Diets (D1 and D2) will be used for investigating the health of 16 dogs.

All dogs are in good health and at the end of three months the cardiovascular health

of the dogs is to be measured.

The JMP datasetdogsprovides information on theGenderandAgeof the 16 dogs.

The aim is to "design" the planned investigation by assigning each dog to one of the

Diets so thatGenderANDAgeare equally distributed (balanced) across both Diets

(a)IfAgeis ignored, how would you "randomly" allocate the Diets to the dogs ?

Explain your reasoning and show your allocation result for the 16 dogs.

(b)Do thedouble-sortof the dogs dataset as per the JMP Notes. Print your result.

(c)Based on the sorted dataset, a "balanced" allocation ofGenderANDAge

cannotbe obtained for each Diet. Explain why.

(d)Bygrouping(categorizing)Ageshow your best "design" for this study
