a) An experimenter, Mr Mafanela would like to investigate the effects of a treatment with five levels A, B, C, D, and E. However he could only afford to take twenty observations in five blocks which could only be of size four each. (i) Sketch the layout of the data. (ii) Check whether Mr Mafanela design is balanced or not.

Teacher X conducted an experimental study entitled the Effect of the Error Analysis Technique in Geometry among Grade 8 students in one of the Junior High Schools in Maryland, USA, which of the following would be the most appropriate interventions? A. Geometry classb. B. Grade 8 students C. Effects of Geometry D. Error analysis technique
An educational psychologist would like to determine whether access to computers has an effect on grades for high school students. One group of n = 16 students has home room each day in a computer classroom which each student has a computer. A comparison group of n = 16 students has home room in a traditional classroom. At the end of the school year, the average grade was recorded for each student. The data are as follows: Computer: Traditional: M = 86 M = 82.5SS = 1005 SS = 1155 A)Is there a significant difference between the two groups on school performance? Use a two-tailed test with α = .05. B)Conduct a 95% confidence interval for the population mean difference between a computer classroom and a regular classroom. (1 pt.) C)Compare your hypothesis test decision and the confidence interval result. Are they consistent with each other? Please explain. (0.5 pt.)
The student government took a poll on a policy they would like to suggest to the dean. The proportion of the first-year students in favor was 40% with a response of 30 students. The second-year students were 55% in favor with a response of 20 students. Is the difference in proportions for the two groups of students statistically significant?
I want to study whether the presence of music has an effect on attention. I conduct an experiment where I recruit 30 students and randomly assign them into 3 groups: rock music, classical music, and white noise. I then give them a task and count the number of times the start to look elsewhere (noting loss of attention to the task). What is the independent variable? c. What is the dependent variable?
Dr. Ortega took a wide sample of people and timed them running a mile. There is a lot of variability in time, with some runners taking 5 minutes and others 20 minutes or more. Analyzing this further, Dr. Ortega wants to know what factors influence running speed? She hypothesizes that physical fitness and age play important roles, as do physical health and weight. For further clarity, Dr. Ortega calculates r2 for each variable and finds that the effect size for physical fitness is 29%.

An experiment is conducted to investigate the toxic effect of three chemicals, A, B, and C on the skin of rats. Three adjacent 1-inch squares are marked on the backs of 8 rats and each of the 3 chemicals is applied to each rat. The squares of the skin are then scored from 0 to 10, depending on the degree of irritation. The data on the outcome of the experiment are given in the following table: Rat 1 2 3 4 5 7 1.0 A B C| Rank A Rank B Rank C 6 5 3 11.5 6.0 1.5 9 8 4 23.0 20.0 3.0 6 11.5 23.0 1.5 6.0 20.0 11.5 16.5 20.0 23.0 6.0 16.5 11.5 11.5 16.5 6.0 11.5 6.0 16.5 5 6 7 8 Σyi 1.0 9 3 8 6 8 9 7 6 7 5 7 50 57 43 10 5 6 6 5 10 For the original data set 1-1 ij = 150, and ₁1-13 = 1006. From the ranks of the original data set the rank sums are RA = 97.5, RB = 128, Rc = 74.5 respectively. At a = 1%, is there sufficient evidence to support the research hypothesis that the probability distributions of skin irritation scores for the 3 chemicals differ in location? (a) Stating relevant…
