COS d) y = arctan X, X-U[0, 1 ]
9. In the context of the technique of gel filtration explain the terms linear range (look it up in the lab manual) and fractionation range. What is the difference in these? 10.One of the assumptions used in the derivation of the Michaelis-Menton equation is that the velocity represents initial velocity. Explain what exactly initial velocity is.

(3) Let XXnX1,X2,⋯,Xn be iidiid random variables with Cauchy(0,1)Cauchy(0,1) distribution. That is, the density of X1 is 1/(π(1+x2)) for x∈ℜ. Prove that (X1+X2+⋯+Xn)/n is again distributed as Cauchy(0,1). The following ``answers'' have been proposed. Please read the choices very carefully and pick the most complete and accurate choice. (a) By the last exercise, the characteristic function of X1, is e−|t|e−|t|. Therefore by the fact that the Xi are iid, the characteristic function of their average is the product of n...
