The table below shows the number of absences, x, in a Statistics course and the final exam grade, y, for 8 students. 4 3 3 7 95 90 90 55 70 80 85 54 Necessary calculations: You may need to find the following quantities to answer the following questions: E-, xi =?, E-1 x =?, E-1 yi =?, E-1 y =?, and E-1xiyi =?. (i) Draw a scatter diagram for the variables x and y and hence indicate what type of relationship exist between them. (ii) Find the sample correlation coefficient and interpret your result.
