Answer
The answer is
[tex]-47.1<\mu<118.7[/tex]
EXPLANATION
Problem Statement
The question tells us to find the trilinear inequality given the confidence interval of the form:
[tex]70.8\pm117.9[/tex]
Solution
To solve this question, we need to rewrite this confidence interval by adding and subtracting 117.9. This will give us a large value and a small value. The large value is above the mean and the small value is below the mean.
With this information, we can proceed to solve the question as follows:
[tex]\begin{gathered} 70.8\pm117.9\colon \\ 70.8+117.9=188.7 \\ AND \\ 70.8-117.9=-47.1 \\ \\ \therefore\text{The trinomial inequality is:} \\ -47.1<\mu<118.7 \end{gathered}[/tex]
Final Answer
The answer is:
[tex]-47.1<\mu<118.7[/tex]
