1) A journal article reports that a sample of size 5 was used as a basis for calculating at 95% CI for the true average natural frequency (Hz) of delaminated beams of a certain type. The resulting interval was (229.764, 233.504). Assume the population is normal. You decide that a confidence level of 99% would be more appropriate than a 95% level used. What are the limits of the 99% interval?
