13. Sampling the forest To gather data on a 1200-acre pine forest in Louisiana, the U. S. Forest Service laid a
grid of 1410 equally spaced circular plots over a map
of the forest. A ground survey visited a sample of 10%
of these plots.
(a) Explain how you would use technology or Table D
to choose an SRS of 141 plots. Your description should
be clear enough for a classmate to obtain
your
results.
(b) Use your method from (a) to choose the first
3 plots.
