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.

A clinical trial is run to assess the effects of different forms of regular exercise on HDL levels in persons between the ages of 18 and 29. Participants in the study are randomly assigned to one of three exercise groups (Weight training, Aerobic exercise or Stretching/Yoga) and instructed to follow the program for 8 weeks. Their HDL levels are measured after 8 weeks and are summarized below. Exercise Group N Mean Standard Deviation Weight Training 20 49.7 10.2 Aerobic Exercise 20 43.1 11.1 Stretching/Yoga 20 57.0 12.5 Is there a significant difference in mean HDL levels among the exercise groups?
