z分布统计表(总3页)
表B.1 正态分布表*
*A列是正态分布的z分数。
B列是z分数对应分布中本体的概率值。 C列是z分数对应分布中尾端的概率值。
主要：因为正态分布是对称分布，所以负的z分数具有与正的z分数相同的概率。(A) (B) (C) (A) (B) Z 本体概率 0.00 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08 0.09 0.10 0.11 0.12 0.13 0.14 0.15 0.16 0.17 0.18 .5000 .5040 .5080 .5120 .5160 .5199 .5239 .5279 .5319 .5359 .5398 .5438 .5478 .5517 .5557 .5596 .5636 .5675 .5714 尾端概率 .5000 .4960 .4920 .4880 .4840 .4801 .4761 .4721 .4681 .41 .4602 .4562 .4522 .4483 .4443 .4404 .43 .4325 .4286 Z 本体概率 0.20 0.21 0.22 0.23 0.24 0.25 0.26 0.27 0.28 0.29 0.30 0.31 0.32 0.33 0.34 0.35 0.36 0.37 0.38 .5793 .5832 .5871 .5910 .5948 .5987 .6026 .60 .6103 .6141 .6179 .6217 .6255 .6293 .6331 .6368 .06 .43 .80 尾端概率 .4207 .4168 .4129 .4090 .4052 .4013 .3974 .3936 .37 .3859 .3821 .3783 .3745 .3707 .3669 .3632 .3594 .3557 .3520 (C) (A) (B) Z 本体概率 0.40 0.41 0.42 0.43 0.44 0.45 0.46 0.47 0.48 0.49 0.50 0.51 0.52 0.53 0.54 0.55 0.56 0.57 0.58 .6554 .6591 .6628 .66 .6700 .6736 .6772 .6808 .6844 .6879 .6915 .6950 .6985 .7019 .7054 .7088 .7123 .7157 .7190 尾端概率 .3446 .3409 .3372 .3336 .3300 .32 .3228 .3192 .3156 .3121 .3085 .3050 .3015 .2981 .2946 .2912 .2877 .2843 .2810 (C) -CAL-FENGHAI.-(YICAI)-Company One1
