(a) what is the rate of heat conduction through the 3.00-cm-thick fur of a large animal having a 1.40-m2 surface area? assume that the animal’s skin temperature is 32.0°c , that the air temperature is −5.00°c , and that fur has the same thermal conductivity as air. (b) what food intake will the animal need in one day to replace this heat transfer?

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
