THE AIR SAFETY CASE DS AlertTimes

Referring to Exercise 8.19 (page 316), regard the sample of 15 alert times for which s = 1.026 as a preliminary sample. Determine the sample size needed to make us 95 percent confident that x, the sample mean alert time, is within a margin of error of .3 second of m, the population mean alert time using the new display panel.
