A genetic experiment involving peas yielded one sample of offspring consisting of 403green peas and 126 yellow peas. Use a 0.05 significance level to test the claim that underthe same circumstances, 35% of offspring peas will be yellow. Identify the null hypothesis,alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, andfinal conclusion that addresses the original claim. Use the P-value method and the normaldistribution as an approximation to the binomial distribution.
