A genetic experiment with peas resulted in one sample of offspring that consisted of 424 green peas and 163 yellow peas.
a. Construct a 95% confidence 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?

3. Assume you borrow $100,000 to purchase a house and the stated interest rate is 5 percent. The loan will be set up as an installment loan with monthly payments. What is the annual percentage rate? Show all work to be eligible for full credit. Discuss why the annual percentage rate is different than the stated interest rate.

A publisher reports that 62% of their readers own a particular make of car. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage. A random sample of 220 found that 56% of the readers owned a particular make of car. Find the value of the test statistic. Round your answer to two decimal places.

A bond that makes annual payments is initially selling at $1,000. It has a 6% coupon rate and 6% YTM. The maturity is 10 years and face value is $1,000. If the YTM falls to 5%, what is the percentage change in the price? Enter as a whole percentage to two decimals with no symbols (e.g if the change is 9.52% enter 9.52).

In a study of the accuracy of fast food drive-through orders, Restaurant A had 211 accurate orders and 56 that were not accurate.
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: 0.188<p<0.271
