Problem 3 [20 points). Environmental regulations require that no more than 30% of any one species be severely affected by human activity related to construction. As part of the evaluation for an environmental impact statement of proposed hydroelectric design on the Stikine River in British Columbia, researchers conducted preliminary investigations of the effect of human-induced disturbances on the behavior of the resident mountain goat population. Goat response to exploration activities, including close-flying helicopters, fixed-wing aircraft, human bipedal movements, and loud blasts from geological drilling activities, were recorded for n 804 goats. The researchers observed that 265 goats displayed a severe flight response to local rock or plant cover. 1. (4 points) Set-up the appropriate null and alternative hypotheses. Ho

Explanation / Answer

H0 : There are no more than 30% of any one species be severly affected by human activity related to construction. The proportion of goats displayed a severe flight response to local rock or plant cover is less than 0.30 . p <= 0.30

Ha : There is more than 30% of any one species be severly affected by human activity related to construction. The proportion of goats displayed a severe flight response to local rock or plant cover is greater than 0.30 . p > 0.30
