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.
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
