Within a study watershed there are six precipitation gauges with the following average annual rainfall [mm] at the following elevations [m]:

GaugeElevations = [442, 548, 736, 770, 852, 1031]

GaugePrecipitation = [1392, 1246, 1495, 1698, 1717, 1752]

Topographic analysis of this watershed gives the following distribution of its area with elevation:

AreaElevations = [200, 400, 600, 800, 1000, 1200, 1400, 1600]

AreaFraction = [0.0, 0.028, 0.159, 0.341, 0.271, 0.151, 0.042, 0.008]

Where the AreaElevations are the upper end of that area's elevation range. For example, 2.8%, of the basins area has an average elevation of 300m (i.e. between 200m and 400m). Given this information, estimate the average annual precipitation that this watershed receives.

A large study finds that a new hypertension drug lowered BP, on average, 1 mm Hg more than conventional treatments. The results were statistically significant with a P Value of less than .05 because the study was large enough to detect a very small difference. Were the results clinically significant? Why or why not?

Within the US Following are three conceptual frameworks for the study of health policy and laws: Framework one consists of three broad topical domains—health care policy and law, bioethics, and public health policy and law. Framework two consists of three historically dominant perspectives—social, political, and economic perspectives. Framework three consists of key stakeholders in the process. In this assignment, you will focus on the government's health's immunization laws that were passed to protect children from infectious diseases. Using the Internet,...
