Question

Express the confidence interval 70.8 + 117.9 in the form of a trilinear inequality

Answer 1

The answer is

`-47.1<\mu<118.7`

Step-by-step explanation

Problem Statement

The question tells us to find the trilinear inequality given the confidence interval of the form:

`70.8\pm117.9`

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:

`\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}`

Final Answer

The answer is:

`-47.1<\mu<118.7`
