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