The competitive advantage of small American factories such as Tolerance Contract Manufacturing lies in their ability to produce parts with highly narrow requirements, or tolerances, that are typical in the aerospace industry. Consider a product with specifications that call for a maximum variance in the lengths of the parts of 0.0004. Suppose the sample variance for 30 parts turns out to be s2 = 0.0005. Use α = 0.05 to test whether the population variance specification is being violated.

A juggler tosses a ring into the air. The height of the ring in feet above the juggler’s hands can be modeled by the function f (x) = -16 x 2 + 16x, where x is the time in seconds after the ring is tossed. Find the ring’s maximum height above the juggler’s hands and the time it takes the ring to reach this height. Then find how long the ring is in the air.
