Past experience has indicated that the breaking strength of yarn used in manufacturing drapery material is normally distributed and that a = 3 psi. A random sample of 8 specimens is tested, and the average breaking strength is found to be 97 psi. Find a 95% two-sided confidence interval on the true mean breaking strength. Round the answers to 1 decimal place. SHS Statistical Tables and Charts
