The breaking strengths of cables produced by a certain manufacturer have a standard deviation of 91 pounds. A random sample of 50 newly manufactured cables has a mean breaking strength of 1700 pounds. Based on this sample, find a 99% confidence interval for the true mean breaking strength of all cables produced by this manufacturer. Then give its lower limit and upper limit. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.) Lower limit: l Upper limit:

Scores on a test taken by 1st graders and 2nd graders were compared to look at development. The five 1st graders sampled got the following scores: 4, 3, 5, 7, 4. The five 2nd graders sampled got the following scores: 7, 9, 8, 6, 9. Compute the 95% confidence interval for the difference between means (2nd graders - 1st graders). You may use the Analysis Lab.
