Essay

Knowledge of where animals forage for food is essential for effective wildlife
management and conservation. The data below are foraging heights (in m) for a
sample of Mountain Chickadees. The data are taken from two different species of fir
trees: the Douglas fir and the White fir. Douglas: $22,15,16,16,16,17,17,17,18,19,19,10,10,13,13,14$ $6,7,7,8,8,9,3$

White: $28,25,21,21,18,18,16,14,14,15,15,15,15,12,12,13$ $13,11,11,8,8,7,5,3$ (a) Display these data using a comparative (back-to-back) stem-and-leaf plot. Use
the stems shown below, and be sure to include all information needed to compare
the two distributions. |OL |

$| 2 \mathrm { H } |$ (b) Compare the distributions in part (a). What differences and similarities do you
observe in the two distributions?
(c) When Mountain Chicadees are sampled to assess their health, they are captured in
mist-nets, which are set to capture the birds at different heights. The mist nets are
about 2 meters high, and directions must be given to the persons who set up the
nests so that the mist-nets are positioned to capture the most birds. Based on the
data from part (a) and your display in part (b), write a short paragraph describing
the appropriate mist-net height in a forest region of Douglas firs and for a forest
region of White firs.

Distinguish between short-run and long-run perspectives in macroeconomic models.

Recognize the implications of Keynesian economics for managing recessions and depressions.

Examine the characteristics of the aggregate supply curve and conditions under which it may shift.

Understand Keynes's explanations for the Great Depression and his policy recommendations.

Capillaries

Tiny blood vessels that connect arteries and veins, facilitating the exchange of water, oxygen, carbon dioxide, and many other nutrients and waste substances between blood and tissues.

Mesenteric Vein

A vein that drains blood from the small intestine (and sometimes from the large intestine) into the portal vein of the liver.

Liver

An essential body organ that plays a crucial role in removing toxins, synthesizing proteins, and producing the biochemicals needed for digestion.
