Step 1 :Given the lower bound of the confidence interval is 22 and the upper bound is 28.
Step 2 :The point estimate of the population mean is the average of the lower and upper bounds of the confidence interval, which is \((22+28)/2 = 25.0\).
Step 3 :The margin of error for the confidence interval is the difference between the point estimate and one of the bounds, which is \(25.0 - 22 = 3.0\).
Step 4 :Final Answer: The point estimate of the population mean is \(\boxed{25.0}\). The margin of error for the confidence interval is \(\boxed{3.0}\).
