A group of 8 students participated in a business department experiment. The Students entered a special training program. Prior to the start of the program the students took a "Pretest" practice examination. After taking the pretest the students received 2 weeks of specialized instruction and tutorial in management and then took a "Post course" departmental exam. Given the paired test exam data is given in the table below:

E\" P Pretest Score 110 110 120 120 130 130 140 140 -M------- Score 110 120 140 150 170 180 200 Construct a scatter diagram for the table data. (3) Do the data scatter plot suggest a linear relationship between pre and post test scores? If so what type of correlation does the data plot suggest? (2) Construct the Correlation Data Analysis table as seen in the ppt presentation. (3) Calculate the Pearson Linear Correlation Coefficient, R. Make sure to show the work / formula you have used and the calculations used to nd R. (3) Based on your computation of R above and using our table for evaluating correlation strength what type of correlation is exhibited and what is the strength the correlation between pre and post test scores?
