A materials engineer is studying a new heat-resistant alloy intended for use in a commercial jet engine, and needs to estimate the average temperature at which the material first loses structural integrity. Preliminary studies of the breaking temperature show a standard deviation of 92 degrees Celsius. If the engineer needs to estimate the mean with a margin of error of 12 degrees Celsius at 99% confidence, how many samples should be observed
