The Bough and Bud Company combined an insect spray with a growth hormone to produce the MOP (More Oranges Production) Treatment, which was expected to increase the number of oranges produced by each tree.
The data below shows the number of oranges produced by each tree in two separate samples of trees.
One group of trees (Group A) had been given the MOP treatment. The other (Group B) was kept under identical conditions but was not given this treatment.
Group A (given the MOP treatment)
34 29 27 82 21 48 55 43 29 76
45 33 56 73 55 29 77 46 31 27
52 28 35 24 50 38 34 48 71 58
Group B (no special treatment)
32 37 56 39 33 61 45 52 38 60
32 44 33 54 40 64 41 29 30 61
41 32 38 32 42 48 56 63 57 33
