    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.
