Answer:
The error bound is of 13.5 corn kernels.
Step-by-step explanation:
Any confidence interval has a lower bound and an upper bound. The error bound is the difference between the values of those two bounds, divided by 2.
In this problem, we have that:
Lower bound: 858.50
Upper bound: 885.50
Error bound: (885.50-858.50)/2 = 13.5
The error bound is of 13.5 corn kernels.
