| The Proportions Against
a Specified Value test is used for large
samples to test the hypothesis:
H0: the proportion is the
same in both populations
H1: the proportion is [different
to/greater than/less than] the specified
value
The value of the Z statistic
is calculated from:

Where:
 |
proportion in the sample |
 |
specified value of the proportion |
| n |
sample size |
The probability corresponding to Z0
can be found from tables.
