6.3.7 A manufacturer wants to assess whether or not rods are being constructed appro- priately, where the diameter of the rods is supposed to be 1.0 cm and the variation in the diameters is known to be distributed Nu, 0.1). The manufacturer is willing to tolerate a deviation of the population mean from this value of no more than 0.1 cm, i.e., if the population mean is within the interval 1.0 +0.1 cm, then...

A personal computer manufacturer is interested in comparing assembly times for two keyboard assembly processes. Assembly times can vary considerably from worker to worker, and the company decides to eliminate this effect by selecting a random sample of 10 workers and timing each worker on each assembly process. Half of the workers are chosen at random to use Process 1 first, and the rest use Process 2 first. For each worker and each process, the assembly time (in minutes) is...
