Question
An experiment is conducted at the significance level of 0.005 to determine whether there is a difference among the mean increases in growth produced by five strains (A, B, C. D and E) of growth hormones for plants. The experimental material consists of 20 cutings of a shrub jal of
equal weight), with four cuttings randomly assigned to each of the five different strains. The increases in weight for each cutting along with the sample mean and sample standard deviation of each group are given in the tabie below
