accounting department at Weston Materials‚ Inc.‚ a national manufacturer of unattached garages‚ reports that it takes two construction workers a mean of 32 hours and a standard deviation of 2 hours to erect the Red Barn model. Assume the assembly times follow the normal distribution. a. Determine the z values for 29 and 34 hours. What percent of the garages take between 32 hours and 34 hours to erect? z(29) = (29-32)/2 = -3/2 z(34) = (34-32)/2 = 1 z(32) = 0 P(32 < x < 34) = P(0< z < 1) = 0

Salmon Population Restoration Salmon populations are a species indicator for their ecosystem‚ meaning the health of their population also indicates the health of their ecosystems. Factors facilitating this notion include‚ that salmon are andromodus and inhabit the entire river ecosystem‚ from headwaters to the ocean. They are also extremely sensitive to changes in the ecosystem. Variables like water quality‚ trophic webs and upstream perturbations‚ turbidity and temperature all affect the salmon
