Answer #1

4.34 is the average (add all up and divide by the number of readings - 6)

Standard Deviation is .023

    The diameter of a spindle in a small motor is supposed to be 4.5 millimeters (mm) with a standard deviation of 0.14 mm. If the spindle is either too small or too large, the motor will not work properly. The manufacturer measures the diameter in a sample of 17 spindles to determine whether the mean diameter has moved away from the required measurement. Suppose the sample has an average diameter of 4.41 mm. Ho: Ha:

    Kane (1986) discusses the concentricity of an engine oil seal groove. Concentric- ity measures the cross-sectional coaxial relationship of two cylindrical features In this case, he studies the concentricity of an oil seal groove and a base cylin der in the interior of the groove. He measures the concentricity as a positive deviation using a dial indicator gauge. Historically, this process has produced an average concentricity of 5.6 with a standard deviation of 0.7. To monitor this process, he periodically...
