Step 1 :The problem provides a confidence interval for the average commute distance of all students attending class at the Okeechobee campus of IRSC, which is (14.4,18.8).
Step 2 :We are asked to determine the point estimate $(\bar{x})$ and margin of error $(E)$ used to construct this particular confidence interval.
Step 3 :The point estimate is the average of the lower and upper bounds of the confidence interval. So, we calculate it as \(\bar{x} = \frac{{14.4 + 18.8}}{2} = 16.6\).
Step 4 :The margin of error is the difference between the upper bound and the point estimate. So, we calculate it as \(E = 18.8 - 16.6 = 2.2\).
Step 5 :Final Answer: The point estimate $\bar{x}$ is \(\boxed{16.6}\) and the margin of error $E$ is \(\boxed{2.2}\).
