Question 916608: An experiment involving peas yielded one sample of offspring consisting of 445 green peas and 153 yellow peas. Use a 0.01 significance level to test the claim that under the same circumstances, 26% of offspring peas will be yellow. Identify the null hypothesis, alternative hypothesis, test statistic, P-value conclusion about the null hypothesis and final conclusion that addresses the original claim. Use the P-value method and the normal distribution as an approximation to the binomial distribution.
What is the test statistic?
z=______
What is the critical value?

You can put this solution on YOUR website! Ho: p = .26
Ha: p ≠ .26
-----------------------------------------
sample proportion = p-hat = 153/598 = 0.226
---
test stat:: z(0.226) = (0.226-0.26)/sqrt[0.26*0.74/598] = -1.8955
-----
critical value = ±2.576
