An experiment is conducted to determine the time evolution of the mean increases in growth produced by growth hormones for plants. The experimental material consists of 20 cuttings of a shrub (all of equal weight), with four cuttings in each of five weekly studies. The increases in weight (in grams) for each cutting along with the sample mean and sample standard deviation of each group are given in the table below. Cutting Cutting Cutting Cutting Mean D Standard Week A B Dev. 19 13 16 12 15 3.1623 2 27 29 25 17 24.5 5.2599 22 22.25 0.5000 14 13.25 1.7078 12 11.75 2.5000 3 22 22 23 4 13 15 11 15 11 (a) Determine the control limits for this study LCL= UCL= (b) In your written work, construct the control chart of this experiment.
