Your help in debugging and improving the new notes is appreciated. -B. Hajek (b-hajek at illinois dot edu)
• page 32, line -12, should be P(ABC)=P(A)P(B)P(C)
• page 44, second line of solution in Example 2.8.3 should begin with "p_X(1)=1"
• page 57, slightly past middle, should be "whether P(H_1 | X=2) > P(H_0 | X=2 )"
• page 70, first and seconds lines, "passenger" should be "passengers," and "An" should be "and"
• page 70, line -6, should be "Suppose the system fails if three or more servers crash."
• page 88, line 3, change "This" to "One way to derive the pdf of \$T_r\$ is to use this"
• page 109. line 7, should be "yields the pdf"
• page 114, fifth line of solution, P{T> epsilon} should be P{T less than or equal to epsilon}
• page 115, third line of last paragraph, change "hypotheses" to "hypothesis"
• page 127, line -4, should be "pdfs f_X and f_Y"
• page 159, solution example 4.8.6 part c: Cov(X_i, X_j) = 0 should be Cov(X_i, Y_j)=0.
• page 171, just above example 4.10.6, the numerical value of L needs to be 0.5 less
• page 172, in the first line, the variable is not D_k, but ln(D_k). This occurs twice in that line.
• page 178, line -5, should be, "where Y and N are uncorrelated"
• page 185, line -10, change X to L in statement of memoryless property
• page 189, Section 2.3 1. 1/3 (not 1/2)
• page 189, Section 2.7 2. 0.2240
• page 189, Section 2.10 1. 0.1705
