The breaking strengths of cables produced by a certain manufacturer have a standard deviation of 98 pounds. A random sample of SO newly manufactured cables has a mean breaking strength of 1900 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
