(a)
To determine: The number of isoprene units in the given terpene and identification of the terpene as a monoterpene, sesquiterpene or diterpene.
Interpretation: The number of isoprene units in the given terpene and identification of the terpene as a monoterpene, sesquiterpene or diterpene are to be stated.
Concept introduction: An isoprene unit is bunched of five-carbon atoms. In terpenes, the isoprene units are connected to each other in head to tail fashion. The head part of an isoprene unit is branched, whereas the tail part of an isoprene unit is un-branched.

Calculate the central, upper, and lower control limits for the c-chart and draw the chart precisely on the graph sheet provided (based on 3-sigma limits). Your chart should include a line for each of the control limits (UCL, CL, and LCL) and the points for each observation. Number the x-axis 1 through 25 and evenly space the numbering for the y-axis. Connect the points by drawing a line as well. Label each line drawn.
