Answer:

Fertilizer B produced a 15% greater yield

Step-by-step explanation:

Mean yield fertilizer A = 20.2

Mean yield fertilizer B = 23.2

Thus, 23.2 − 20.2

20.2

= 0.1485 ≈ 0.15 or 15%

Answer : The correct option is, (B) Fertilizer B produced a 15% greater yield

Step-by-step explanation :

First we have to calculate the total yield of potato with fertilizer A.

Total yield of potato with fertilizer A = (27 + 20 + 16 + 18 + 22 + 19 + 23 + 21 + 17 + 19) kg

Total yield of potato with fertilizer A = 202 kg

Now we have to calculate the total yield of potato with fertilizer B.

Total yield of potato with fertilizer B = (28 + 19 + 18 + 21 + 24 + 20 + 25 + 27 + 29 + 21) kg

Total yield of potato with fertilizer B = 232 kg

Now we have to calculate the percent yield.

[tex]\text{Percent yield}=\frac{232-202}{202}\times 100[/tex]

[tex]\text{Percent yield}=14.85\% \approx 15\%[/tex]

From this we conclude that, the fertilizer B produced a 15% greater yield.

Hence, the correct option is, (B) Fertilizer B produced a 15% greater yield
