During construction of the asphalt concrete layer of asphalt pavement, cores were taken at random after compaction to detect any construction problem and to ensure that the density is within the specification limits. The target value was set at 148.2 pcf and the upper and lower specification limits were set at 148.9 and 147.5 pcf, respectively. The density data shown in Table were collected .a. Using a spreadsheet program, create a control chart for these data showing the target value and the upper and lower specification limits. Are the density data within the specification limits?b. Comment on any trend and possible reasons.
