Answer:
The sample of farms required should be 550 large.
Step-by-step explanation:
Let the sample =K,
mean=np=100
Standard deviation==500
probability =Z=0.90
from the normal probability formula,
Z=
0.9=
500 X 0.9=K-100
450=K-100
K=450+100=550
Hence, the sample of farms required should be 550 large.
