A genetic experiment involving peas yielded one sample of offspring consisting of 414 green peas and 153 yellow peas. Use a 0.01 significance level to test the claim that under the same circumstances, 25% of offspring peas will be yellow. Identify the null hypothesis, alternative hypothesis, test statistic, P-vahie, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-vahie method and the normal distribution as an approximation to the binomial distribution.

What is the test statistic?
What is the P=Value?
What is the conclusion about the null hypothesis?
