Previous record has indicated that the breaking strength of cables used in textile industries is normally distributed with a known variance of 25KN/m². A random sample of ten cables is tested resulting in the following yields: 250 225 190 188 210 210 198 230 233 231 Construct a 98% confidence interval on the true average breaking strength.
