The propagation of fatigue cracks in various aircraft parts has been the subject of extensive study in recent years. The accompanying data consists of propagation lives (flight hours/104) to reach a given crack size in fastener holes intended for use in military aircraft ("Statistical Crack Propagation in Fastener Holes under Spectrum Loading," J. Aircraft, 1983: 1028-1032): Compute and compare the values of the sample mean and median. By how much could the largest sample observation be decreased without affecting the value of the median?
