A random sample of 275 bolts from machine A contained 27 defective bolts, while an independently chosen, random sample of 300 bolts from machine B contained 27 defective bolts. Let p, be the proportion of the population of all bolts from machine A that are defective, and let p, be the proportion of the population of all bolts from machine B that are defective. Find a 90% confidence interval for p, -p,. Then find the lower limit and upper limit of the 90% confidence interval. Carry your intermediate computations to at least three decimal places. Round your responses to at least three decimal places. (If necessary, consult a list of formulas.) Lower limit: Upper limit:
