Any views on part (d) of the following question would be very much appreciated. Thank you "The weight of 80 bags of rice are measured. The table summarises the results: Minimum 480g Lower Quartile 500g Median 540g Upper Quartile 620g Maximum 720g a) Draw a box plot to show this information b) Write down the interquartile range for these data c) How many bags weigh (i) less than 480g (ii) less than 500g d) Draw a cumulative frequency diagram to show the information." The axes and grid are given for plotting. The x axis is labelled Weight (g) and graduated such that there is indication of missing section for lower values of weight and then 500 550 ..up to .. 700 The Mark Scheme says "5 correct plots" are required. The Examiners' Report says, "Some candidates plotted four of the points but omitted the point corresponding to a cumulative frequency of 0 at 480g"
