(a)[1]
One orange is selected at random. Find the probability that its mass is greater than $200\text{ g}$.
(b)[3]
Calculate an estimate for the mean mass.
(c)[3]
On the grid on the next page, draw a cumulative frequency diagram for the masses of the oranges.
(d)[1]
Use your graph to estimate the median.
(e)[2]
Oranges with mass above $T\text{ g}$ are called ‘Class A’. $20\%$ of the oranges are in ‘Class A’. Use your graph to find $T$.
(f)[1]
Oranges with mass of $178\text{ g}$ or less are used to make orange juice. Use your graph to estimate how many of these oranges there are.
