2. When deriving, we assumed thatfor all where. Show that this is true assuming the standard assumptions hold.
3. The data in the table below show the measurements of hemoglobin (g per 100 ml) in the blood of brown trout. The trout were placed at random in four different troughs. The fish food added to the troughs contained, respectively, 0, 5, 10, and 15 grams of sulfamerazine per 100 pounds of fish (coded 1, 2, 3, and 4). The measurements were made on 10 fish randomly selected from each trough after 35 days.
