A random sample of 200 bolts from machine A contained 22 defective bolts, while an independently chosen, random sample of 400 bolts from machine B contained 40 defective bolts. Let p₁ be the proportion of the population of all bolts from machine A that are defective, and let p₂ be the proportion of the population of all bolts from machine B that are defective. Find a 90% confidence interval for p₁ -P2. 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: -0.0541 X Upper limit: 0.0341 E

Suppose that a random sample of 11 adults has a mean score of 79 on a standardized personality test, with a standard deviation of 7 . (A higher score indicates a more personable participant.) If we assume that scores on this test are normally distributed, find a 90% confidence interval for the mean score of all takers of this test. Then find the lower limit and upper limit of the 90% confidence interval
