Answer:
(0.23, 0.30)
Explanation:
Number of green peas = 428
Number of yellow peas = 155
Total number of peas = n = 583
Since we have to establish the confidence interval for yellow peas, the sample proportion of yellow peas would be considered as success i.e. p =

q = 1 - p =

Confidence Level = 95%
Z value associated with this confidence level = z = 1.96
Confidence interval for the population proportion is calculated as:

Using the values, we get:

Conclusion:
We are 95% confident that true value of population proportion of yellow peas lie between 0.23 and 0.30
