Question 47

An agricultural scientist investigated the effect of two different soil treatments on the yield of a new hybrid tomato strain. Group 1 received 'Treatment X' (organic compost), while Group 2 received 'Treatment Y' (synthetic chemical fertiliser). The yield per plant (in kg) was recorded for each group, and the results are summarised in Table 3.

Table 3: Median tomato yield and range for both soil treatments
