1. An experiment was conducted to determine the effect of three (3) baking times (30 mins, 35mins, 40mins) on the height of cassava bread loaf. Nine loaf pans were prepared, each containing equal amounts of dough from a single batch of dough. Each baking time was randomly assigned to three loaf pans. Identify the following: a. treatment in the experiment; b. treatment level; c. experimental units; and d. response variable.

2. In a field trial, an agriculturist wanted to compare the yield of different cultivars of sugar beet. He intends to divide the field into 12 plots. For each plot, the same number of seeds will be sowed in furrows with equal depths. Then the yield will be measured after 80 days. Identify the following: a. Treatment;

b. Experimental units; and c. Response variable.

3. An experiment is to be conducted to examine the effect of different fertilizer applications on the yield of potatoes. The researcher will examine 4 distinct fertilizer applications (F1, F2, F3, and F4). Show a field lay out and discuss how you randomize the different experimental units. (Note: use 4 replications)
