Breaking strengths of a random sample of 21 molded plastic housing were measured, and a sample standard deviation of S-19.52 was obtained. A confidence interval (439.23, 460.77) for the average strength of molded plastic housings were constructed from these results. What is the confidence level of this confidence interval? Solution:
