Web traffic can be measured to help highlight security
Chapter 15, Problem 14E(choose chapter or problem)
Web traffic can be measured to help highlight security problems or indicate a potential lack of bandwidth. Data on Web traffic (in thousand hits) from http://en.wikipedia.org/wiki/Web_ traffic are given in the following table for 25 samples each of size 4.
(a) Use all the data to determine trial control limits for \(\bar{X}\) and R charts, construct the chart, and plot the data.
(b) Use the trial control limits from part (a) to identify out-of-control points. If necessary, revise your control limits, assuming that any samples that plot outside the control limits can be eliminated.
