Title: Understanding Confidence Intervals in Trilnear Inequalities---**Expression of Confidence Interval**In statistical analysis, a confidence interval provides a range of values that is likely to contain a population parameter. The given task is to express the confidence interval in the form of a trilinear inequality.**Problem Statement:**Express the confidence interval $21.4\% \pm 4.5\%$ in the form of a trilinear inequality.**Instructions:**- Calculate the lower bound of the confidence interval by subtracting the margin of error from the given percentage.- Calculate the upper bound by adding the margin of error to the given percentage.- Format the result as a trilinear inequality.---**Calculation:**1. **Given values:** - Confidence Interval: $21.4\%$ - Margin of Error: $\pm 4.5\%$2. **Lower Bound Calculation:** \[ 21.4\% - 4.5\% = 16.9\% \]3. **Upper Bound Calculation:** \[ 21.4\% + 4.5\% = 25.9\% \]4. **Trilinear Inequality Format:** \[ 16.9\% < p < 25.9\% \]**Conclusion:**The confidence interval $21.4\% \pm 4.5\%$ can be expressively and effectively stated as the trilinear inequality $16.9\% < p < 25.9\%$. This represents the range within which the true population parameter $p$ is expected to lie with a certain level of confidence.

A researcher hypothesizes that ambient air carbon monoxide pollution levels at a certain location should be higher in the winter than they are in the summer. The reasoning behind this hypothesis is that a major source of carbon monoxide in the air is from the incomplete combustion of fuels, and fuels tend to burn less efficiently at low temperatures. Moreover, it is felt that the stagnant winter air is more likely to trap the pollution. In order to investigate this hypothesis, the data set in DS 9.7.12 is collected which shows the ambient air carbon monoxide pollution levels (parts per million) for ten Sunday mornings in the middle of winter and ten Sunday mornings in the middle of summer.
