Errata and Minor Changes
- Chapter 1

otin B \}
- p.7, last display - should read A \cap B^c = \{s : s\in A \hbox{ and } s \notin B \}
- p. 21, in the proof of Theorem 1.5.1 the formula should be P(A_i\cap B)=P(A_i)P(B|A_i) (thanks to Tom Wehrly)
- Chapter 2
- p. 34 - Example 2.1.2, should say Y(clear) = 7/8 instead of Y(rain)=7/8.
(thanks to Ryan Dubay)
- p. 39 - it seems that the Kindle version is missing this
page.
(thanks to Steven Kern)
- p. 73, Exercise 2.5.8, - the definition of F_Y should be changed to
F_Y(y)=1-(1-y)^3 for 1/2 \leq y \leq 1. (thanks to Thomas Wehrly and his students)
- p. 83 Figure 2.7.1 is actually the plot of $F_{X,Y} (x,y)= x^2y$.
(thanks to Nick Souza)
- p. 124 Exercise 2.10.8 the density should be 3sqrt(x)/2 (thanks to Jason Hrncir)
- Chapter 3
- Some of the Theorems concerning expectations do not state that
the relevant expectations actually exist and this
should be considered as being implicit, e.g.
Theorems 3.1.2, 3.1.3, 3.1.4, 3.2.2, 3.2.3, 3.2.4. (thanks to Csaba Szepesvari)
- p. 149 in display 3.3.1, \sigma^2_x should be \sigma^2_X. (thanks to Thomas Wehrly and his students)
- p. 150 In the second last line on this page the ;ast equality should be
E((aX+b-a\mu_X-b)^2) as there is a minus sign missing on the last b.
(thanks to Jared Becksfort)
- p.156 Definition 3.3.4 should have the condition that both variances are positive since Corr is not defined when either variance equals zero.
(thanks to Thomas Wehrly and his students)
- p. 166, Example 3.4.8 The equation
Var(X) = E(X^2) - (E(X)) should have (E(X))^2 instead of (E(X)).
(thanks to Ray Hinton)
- Chapter 4
- Chapter 5
- Example 5.3.2 - the Exponential(1.5) distribution should have been
labelled as the Exponential(2/3) distribution to reflect the fact that we
parameterize the exponential distribution in the book by the rate
rather than the mean. (thanks to Daren Cline)
- p. 280 in problem 5.4.15(d). The factor (N-n)/(N-1) is referred to as the "finite sample correction factor" and should
have been called the "finite population correction factor". (thanks to Carl Mueller)
- Chapter 6
- p. 318, problem 6.2.10 should refer back to problem 2.6.17 not 2.6.12.
(thanks to Noah Alderton)

have left-hand endpoint equal to \hat{psi}_{(1-\gamma)/2}. (thanks to Thomas
Wehrly and his students)
- Chapter 7
- p. 380, l. 4 The comment in parentheses should read "recall that
$\theta_k= 1 - \theta_1 ... - \theta_{k-1}". (thanks to Raymond Hinton).
- p. 385 The reference to Problem 4.6.13 at the bottom of this page (3 lines from the bottom) should be to Problem 4.6.16. (Thanks to Zach Fuller)
- p. 424 - the fourth line should read nx_{bar} = 5, instead of nx_{bar} = 2.3 (thanks to Travis Lilley)
- Chapter 8
- p. 458, Problem 8.2.16 - First part of the problem should have
(\sigma_0)^2 < (\sigma_1)^2. (thanks to Daren Cline and his students)
- Chapter 9
- Chapter 10
- Chapter 11
- p. 629, in Example 11.2.12 P_1(X_3=2) = \sum_{k \in S} \sum_{l \in S} p_{1k} p_{kl} p_{l3} should be P_1(X_3=2) = \sum_{k \in S} \sum_{l \in S} p_{1k} p_{kl} p_{l2}. (thanks to Kent Gauen)
