Transcribed Image Text:A genetic experiment with peas resulted in one sample of offspring that consisted of 430 green peas and 152 yellow peas.
a. Construct a 90% confidence interval to estimate of the percentage of yellow peas.
b. 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?
a. Construct a 90% confidence interval. Express the percentages in decimal form.
(Round to three decimal places as needed.)
