d. Given that raw milk sells for $10 per hundredweight, define a BLUE for the expected marginal revenue per cow obtained from administering the growth hormone. If the total cost of the hormone treatment per cow over the entire lactation is $12 per cc, and if the maximum allowable dose is 10 cc, is it profitable for Smith's to utilize the hormone based on the BLUE estimate of marginal revenu~

calculated above? Why or why not? If so, determine what level should be administered, and provide a BLUE estimate of the gain in profitability.
