8. Past experience has indicated that the breaking strength of yarn used in manufactur-
ing drapery material is normally distributed and that a 2psi. A random sample of 9
specimens is tested, and the average breaking strength is found to be 98 psi. Find a 95%
two -sided confidence interval on the true mean breaking news.

Gauge pressure is the pressure read by a pressure gauge. The gauge pressure will be zero if the pressure is the same as the general atmospheric pressure, because the gauge measures only the excess above atmospheric pressure. The actual pressure will thus be atmospheric pressure plus gauge pressure. Atmospheric pressure is about 14 pounds per square inch. The Rankine temperature scale is the Fahrenheit verson of the absolute temperature, and absolute zero in Rankine is about -460 F. Now, imagine a football has been stored in a warm locker room at a temperature of 71 F, and has a gauge pressure of 12.5 pounds per square inch. Next, it is taken outside and cooled to 40 F. What will the gauge pressure be after this is done?
