The breaking strengths of cables produced by a certainmanufacturer have a standard deviation of 91 pounds. A randomsample of 90 newly manufactured cables has a mean breaking strengthof 1700 pounds. Based on this sample, find a 95% confidenceinterval for the true mean breaking strength of all cables producedby this manufacturer. Then complete the table below. Carry yourintermediate computations to at least three decimal places. Roundyour answers to one decimal place. (If necessary, consult a list offormulas.)
