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 16 27 25 10 10 Plant 2 17 25 23 19 11 Plant 3 10 19 23 16 6 Plant 4 8 29 22 13 9 Mean 12.75 25 23.25 14.5 9 Standard Dev. 4.4253 4.3205 1.2583 3.8730 2.1602 It is also given that the overall mean = 16.9. Compute the following: (a) SSTR= (b) SSE = (c) MSTR = (d) MSE = (e) F =
Applying one way ANOVA on above data:
Source of Variation | SS | df | MS | F |
Between Groups | 765.3 | 4 | 191.325 | 16.078 |
Within Groups | 178.5 | 15 | 11.9 | |
Total | 943.8 | 19 |
a)SSTR =765.3
b)SSE =178.5
c) MSTR = 191.325
d)
MSE =11.9
e) F = 16.078

Problem 3 An experiment is conducted to determine whether the firing oven temperature affects the mean density of a certain type of brick. Multiple bricks are fired at different oven temperatures and the density is measured. The experiment led to the following data (shown in the order in which it was collected) e Minitab for this problem observation Oven Temperature (o Brick Densit 113.1 164.1 113.7 1900 2000 1800 1800 1950 1950 1900 1950 1900 2000 2000 1900 1950 1900...

The NIH wants to compare the mean weight loss for five different diets. They measure the weight loss (in pounds) of 5 men F25 assigned to each of the diets for one month. The resulting data set is below.

Want to know the steps for these questions, please?Use the following information for questions 33 – 42.A dietitian wanted to test three different diets to find out whether or not the mean weight loss for each of these diets is the same. He randomly selected 15 overweight persons, randomly divided them into three groups, and put each group on one of the three diets. The table shown below records the weights lost by these persons after being on these diets...
