An experiment is conducted to determine whether there is a differnce 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 cuttings of a shrub (all 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 table below. A B C D E Plant 1 15 15 15 15 23 23 17 17 15 15 Plant 2 15 15 23 23 21 21 15 15 8 8 Plant 3 15 15 24 24 21 21 16 16 14 14 Plant 4 16 16 17 17 20 20 15 15 13 13 Mean 15.25 15.25 19.75 19.75 21.25 21.25 15.75 15.75 12.5 12.5 Standard Dev. 0.5000 0.5000 4.4253 4.4253 1.2583 1.2583 0.9574 0.9574 3.1091 3.1091 It is also given that the overall mean = 16.9. Compute the following: (a) SSTR= = (b) SSE = = (c) MSTR = = (d) MSE = = (e) F = =

A medical researcher wants to determine whether there is a difference in the mean length of time it takes three types of pain relievers to provide relief from headache pain. Several headache sufferers are randomly selected and given one of the three medications. Each headache sufferer records the time (in minutes) it takes the medication to begin working. The results are shown in the table. At a α = 0.01, can you conclude that the mean times are different? Assume...
