) A forest resource manager is interested in estimating the number of dead fir trees in a 300-acre area of heavy infestation. Using an aerial photo, she divides the area into 200 1.5 acre plots. Let x denote the photo count of dead firs and y the actual ground count for a simple random sample of 10 plots. The total number of dead fir trees obtained from the photo count is 4200. Estimate the total number of dead firs in the 300 acre area and place a bound on the error of estimation.
