Homework Assignments
1. Due September 11: From Durrett, Chapter 1: p. 24 #3, 5, 8, 14
2. Due September 18: From Durrett, Chapter 1: p. 25 #20 ,23, 29, 33, 35, 38.
R problem from last week (R handout: p.38 #6)
3. Due September 25: From Durrett, Chapter 1: p. 27 #40, 48, 50 (To save time, find the distribution by hand and use R to compute the means and variances of the random variables). 53, 55 (explain your answer).
(i) Problem at the bottom of DiceSimulation.R.
(ii) A random variable X has P(X=x)=1/10 for x=0,1,...,9, and P(X=x)=0 otherwise. Determine the mean and variance of X. It's useful to recall that the sum of the squares of the first n natural numbers is n(n+1)(2n+1)/6.
