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

To determine which fertilizer is generally more effective, we can calculate the average weight for each group of potato plants.
For Fertilizer A:
(27 + 20 + 16 + 18 + 22 + 19 + 23 + 21 + 17 + 19) / 10 = 192 / 10 = 19.2 kg
For Fertilizer B:
(28 + 19 + 18 + 21 + 24 + 20 + 25 + 27 + 29 + 21) / 10 = 212 / 10 = 21.2 kg
On average, the potato plants treated with Fertilizer B had a higher weight, so Fertilizer B is generally more effective.
