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