Question

wanted separately for
es, with the same precision?
4.4 In a wireworm survey the number of wireworms per acre is to be estimated with
a limit of error of 30%, at the 95% probability level, in any field in which wireworm
density exceeds 200,000 per acre in the top 5 in. of soil. The sampling tool measures
9x9x5 in. deep. Assuming that the number of wireworms in a single sample follows a
distribution slightly more variable than the Poisson, we take S2 = 1.2 Ý. What size of simple
random sample is needed? (1 acre = 43,560 sq ft.)​

Answer 1
