Question:

Refer to the randomized block design setup to compare the mean costs estimated by four DOT engineers, Examples 13.2 and 13.3.

a. Write the model for each observation of estimated cost y for engineer B. Sum the observations to obtain the average for engineer B.

b. Repeat part a for engineer D.

c. Show that (y̅_B - y̅_D) = β₂ + (ɛ̅_B - ɛ̅_D) Note that the β’s for blocks cancel when computing this difference.
