Confidence intervals are constructed to estimate the range of values that the population parameter (such as population mean or proportion) is likely to fall within. This range is based on the sample statistics (such as sample mean or proportion), which is why the confidence interval is calculated from the sample data. Therefore, the correct choice is C – to bracket the population parameter.
