A construction company is suspicious that the alloy beams they are receiving at a construction site have masses that are on average lighter than what the manufacturer claims to be sending out. They asked for an audit of beam weight measurements from the manufacturer to compare with their on- site weights. The results from their comparisons are given in the table below: Alloy sample 1 34 Manufacturer's mass (kg) 165 201 192 198 155 141 150 187 161 195 193...

An indium-gallium-arsenide-nitrogen alloy developed at Sandia National Laboratory is said to have potential uses in electricity- generating solar cells. The new material is expected to have a longer life, and it is believed to have a 40% efficiency rate, which is nearly twice that of standard silicon solar cells. The useful life of a telecommunications satellite could be extended from 10 to 15 years by using the new solar cells. What rate of return could be realized if an extra...
