Hi! Can someone explain these to me?

Question 1.

A genetic experiment with peas resulted in one sample of offspring that consisted of 434 green as and 151 yellow peas.

1. Construct a 95% confidence interval to estimate of the percentage of yellow peas. Express the percentages in decimal form.
2. Based on the confidence interval, do the results of the experiment appear to contradict the expectation that 25% of the offspring peas would be yellow?

Question 2.

In a study of the accuracy of fast food drive-through orders, Restaurant A had 306 accurate orders and 55 that were not accurate. Express the percentages in decimal form.

a. Construct a 90% confidence interval estimate of the percentage of orders that are not accurate.

b. Compare the results from part (a) to this 90% confidence interval for the percentage of orders that are not accurate at Restaurant B: 0.141

What do you conclude?
