Testing a proportion using critical regions follows a similar process to testing a mean. The main difference is that a proportion represents a probability rather than a measurement. When using critical regions to test a proportion, if the sample test statistic falls within the critical region, the null hypothesis is rejected, and if it falls outside the critical region, the null hypothesis is not rejected. The test statistic is the z-score calculated from the sample proportion and null hypothesized proportion.

EXAMPLE: Testing , Critical Regions
A botanist has produced a new variety of hybrid wheat that is better able to withstand drought than
other varieties. The botanist knows that for the parent plants, the proportion of seeds germinating is
80%. The proportion of seeds germinating for the hybrid variety is unknown, but the botanist claims
that it is 80%. To test this claim, 400 seeds from the hybrid plant are tested, and it is found that 312
germinate. Use a 5% level of significance to test the claim that the proportion germinating for the
hybrid is 80%.
