File name : 'GetZ.m'. This file can be used
for quickly obtaining the z-value for certain values
of alfa
Z-values for all values of alfa between 0.01 and 0.99 for one
tailed and two-tailed tests
One input values : 'alfa','tail'
One output value : 'z'

alfa : significance level (value between 0 and 1)
tail: one-tailed = 'one' two-tailed = 'two'
z: z-score

Input syntax : GetZ(alfa,tail)
NOTE: Only the above-mentioned values for alfa can be used as
input argument
