In 1879, A.A. Michelson measured the velocity of light in air using a modification of a method proposed by the French physicist Foucault. Twenty of these measurements are in table 6E.27 (the value reported is in kilometers per second and has 299,000 subtracted from it). Use these data to set up individuals and moving range control charts. Is there some evidence that the measurements of the velocity of light are normally distributed? O the measurements exhibit statistical control? Revise the control limits if necessary.
Answer to relevant QuestionsThe data shown in Table 6E.2 are x and R values for 24 samples of size n = 5 taken from a process producing bearings. The measurements are made on the inside diameter of the bearing, with only the last three decimals ...Reconsider the hardness measurements in Exercise 6.62. Construct an individuals control chart using the median of the span-two moving ranges to estimate variability. Compare this control chart to the one constructed in ...In the semiconductor industry, the production of microcircuits involves many steps. The wafer fabrication process typically builds these microcircuits on silicon wafers, and there are many microcircuits per wafer.
