ABSTRACT
Proportional parts have not been given in this region because they would not be of sufficient accuracy.
The left-hand column gives the ordinate of the standard normal distribution (i.e. the normal distribution having mean 0 and standard deviation 1), z being listed in the second column. The rest of the table gives , where Z is a random variable having the standard normal distribution. Locate z, expressed to its first decimal place in the second column, and its second decimal place along the top or bottom horizontal: the corresponding table entry is Φ(z). Proportional parts are given for the third decimal place of z in part of the table. These proportional parts should be subtracted if z<0 and added if z>0. EXAMPLES: Ф(−1.2)=Prob (Z≤−1.2)=0.1151; Ф(−1.23)=0.1093; Ф(−1.234)=0.1086.
