A sample of 80 fibers is tested from this shipment; the sample breaking strength is found to be 49.1 N with a standard deviation of 5.2 N. Find a 99% confidence interval for the mean breaking strength of the fibers. Find a 99% confidence interval that gives a lower bound on the mean breaking strength of the fibers. State an accurate interpretation of what the confidence interval actually means. Also, state at least one misinterpretation.
