A process that manufactures glass sheets is supposed to be calibrated so that the mean thickness  of the sheets is more than 4 mm. The standard deviation of the sheet thicknesses is known to be well approximated by σ = 0.20 mm. Thicknesses of each sheet in a sample of sheets will be measured, and a test of the hypothesis H_0:μ≤4 versus H_1:μ>4 will be performed. Assume that, in fact, the true mean thickness is 4.04 mm. a) If...

The highway department is testing two types of reflecting paint for concrete bridge end pillars. The two kinds of paint are alike in every respect except that one is orange and the other is yellow. The orange paint is applied to 12 bridges, and the yellow paint is applied to 12 bridges. After a period of 1 year, reflectometer readings were made on all these bridge end pillars. (A higher reading means better visibility.) For the orange paint, the mean...
