Question

Water samples of 100 cc each are taken periodically from a waste water plant run off. The density of the harmful lime is the parameter of interest. Suppose 25 samples gave an average particle count of 150 per sample. Estimate the particle density, per cubic centimeter, and place a bound on the error of estimation.
