Construct a 90% confidence interval

A genetic experiment with peas resulted in one sample of offspring that consisted of 443 green peas and 155 yellow peas. a. Construct a 90% condence interval to estimate of the percentage of yellow peas. b. It was expected that 25% of the offspring peas would be yellow. Given that the percentage of offspring yellow peas is not 25%, do the results contradict expectations? a. Construct a 90% condence interval. Express the percentages in decimal form.
