Question

Refer to Exercise 15.2. The horticulturist is planning a new study involving modifications to several of the methods of irrigation. In the previous study, it was somewhat cumbersome having blueberry growers implement five different methods of irrigation on their farms, and she wants to know if using the 10 farms as levels of a blocking factor was necessary. If not, she plans to use a single irrigation method on each of n farms.
a. Compute the relative efficiency of the farms as a blocking variable.
b. How many farms would she need in a completely randomized design to have the same precision as was achieved in the randomized block design?
