(a)[2]
On the grid, draw a cumulative frequency diagram to show these results.
(b(i))[1]
From your diagram, estimate the median.
(b(ii))[2]
From the diagram, estimate the interquartile range.
(c)[2]
Ravi also grows tomatoes. The masses of $200$ of his tomatoes are recorded as well. For Ravi’s tomatoes, the median mass was $124\,\text{g}$ and the interquartile range of the masses was $12\,\text{g}$.\n\nMake two comments comparing the masses of tomatoes grown by Lim with those grown by Ravi.
(d(i))[1]
Fill in the frequency table for the masses of tomatoes grown by Lim.
(d(ii))[1]
State the modal class.
(d(iii))[3]
Calculate a mean-mass estimate for these tomatoes.
