A journal article reports that a sample of size 5 was used as a basis for calculating a 95% CI for the true average natural frequency (Hz) of delaminated beams of a certain type. The resulting interval was (229.664, 233.404). You decide that a confidence level of 99% is more appropriate than the 95% level used. What are the limits of the 99% interval? [/Hint/: Use the center of the interval and its width to determine / x/ and / s/.] (Round your answers to three decimal places.)
