Problem 1. a) Let X₁ and X₂ equal the number of pounds of butterfat produced by two Holstein cows one selected at random from those on the Koopman farm and one selected at random from those on the Vliestra farm, respectively) during the 305-day lactation period following the births of calves. Assume hat the distribution of X₁ is N(µx₁ = 693.2, σ²₁ = 22820) and the distribution of X₂ is √(μx₂ = 631.7,0 = 19205). Moreover, let X₁ and X₂ be independent.
