A forester wishes to estimate the average height of trees on a plantation. The plantation is divided into quarter-acre plots. A simple random sample of 20 plots is selected from the 386 plots on the plantation. All trees on the sampled plots are measured, with the results as shown in the accompanying table. Estimate the average height of trees on the plantation and place a bound on the error of estimation. [Hint: the total for cluster i can be found by taking times the cluster average
