in one of Mendel's famous hybridization experiments 8023 offspring peas were obtained, and 24.94% had green flowers the others had white flowers. Consider a hypothesis test that use a 0.05 significance level to test the claim that green flowered peas occur at a rate of 25%/

Yes please..

The null hypothesis in this case is that the proportion of green flowered peas among the offspring would be $p_0=24.94\%=0.2494$. You want to test the alternative hypothesis that says the proportion is $\hat{p}=25\%=0.25$.

To compute the test statistic, you'll need to evaluate the following:
$$Z=\frac{p_0-\hat{p}}{\sqrt{\dfrac{p_0(1-p_0)}{n}}}$$
where $n$ is the sample size of 8023.

Sorry, that numerator is wrong, should be $\hat{p}-p_0$.
