It was reported that majority of the candidates who attempted this question performed very well especially in parts (a) and (b).  They were able to represent the data on a scatter diagram, compute the means (x‾) of x and (y‾) of y correctly, as (x‾) =228/10  = 22.8 and (y‾) =115/10  = 11.5. Fewer candidates were able to draw the line of best fit passing through the point (x‾,y‾). They were able to obtain the relationship between x and y using the expression y = mx + c where m is the slope of the line and is equal to -0.67, c = intercept on the y –axis = 27.  i.e. y = -0.67x + 27.  The value of y when x = 24, which should be obtained from the graph, was 10.5.
