Determine the random allocation of experimental units to the treatments in a completely randomized design with

(a) ???? = 3 treatments, ???? = 20 experimental units, and treatment replications ????1 =

7, ????2 = 7, and ????3 = 6.

(b) ???? = 4 treatments, ???? = 30 experimental units, and treatment replications ????1 =

8, ????2 = 8, ????3 = 8, and ????4 = 6.

(c) ???? = 3 treatments, ???? = 30 experimental units, and balanced treatment replication.

(d) ???? = 5 treatments, ???? = 30 experimental units, and balanced treatment replication.
