Question

Two fertilizers are applied to randomly selected potato plants. After several weeks, the potatoes are weighed. The weights in kilograms are as follows. Which fertilizer is generally more effective?

Fertilizer A: 27, 20, 16, 18, 22, 19, 23, 21, 17, 19
Fertilizer B: 28, 19, 18, 21, 24, 20, 25, 27, 29, 21

(1 point)

Fertilizer B is generally more effective, because the mean and median weights of the potatoes that were treated with it are higher.

Fertilizers A and B are both ineffective, because there is no difference in the ranges of the weights of the potatoes.

Fertilizer A is generally more effective, because the mean and median weights of the potatoes treated with it are higher.

Fertilizers A and B are equally effective, because the ranges of the weights of the potatoes are the same.

Answer 1

Fertilizer B is generally more effective, because its mean and median are higher.

Calculations:
- A: mean = 202/10 = 20.2 kg, median = (19 + 20)/2 = 19.5 kg
- B: mean = 232/10 = 23.2 kg, median = (21 + 24)/2 = 22.5 kg

(Their ranges are both 11, but B’s higher mean and median indicate greater effectiveness.)
