Question

Express the confidence interval 34.5% ± 5.6% in the form of a trilinear inequality.

Answer 1

To express the confidence interval 34.5% ± 5.6% in the form of a trilinear inequality, we can create two separate inequalities for the upper and lower bounds of the interval.

Lower bound:
34.5% - 5.6% ≥ x
28.9% ≥ x

Upper bound:
34.5% + 5.6% ≤ x
40.1% ≤ x

Combining these two inequalities, we have:
28.9% ≥ x ≤ 40.1%
