Table A.1 Standard Normal Areas [Z is N(0,1)]

Figure A.1 gives the total area under the standard normal distribution between 0 and any point z₀ on the positive z-axis (e.g., for z₀ = 1.96, A(z₀) = 0.475).

Table A.2 Quantiles of the t Distribution (T is t_v)

Figure A.2 Given degrees of freedom v, the table gives either: (a) the one-tail t_α,v value such that P(T ≥ t_α,v) = α; or (b) the two-tail values for which (e.g., for v = 15 and α = 0.05, t_{0.05, 15} = 1.753 while t_0.025,15 = 2.131).

Table A.3 Quantiles of the Chi-Square Distribution (X is )
