Which 95% confidence interval for the predicted glia-neuron ratio should be used to test if human brains fit the trend observed for other species? 1. The 95% confidence interval for the mean glia-neuron ratio of all species, which have ln(brain mass) equal to that of humans. OR 2. The 95% confidence interval for the glia-neuron ratio of a randomly drawn species with a ln(brain mass) equal to that of humans. Is the answer 1 or 2?
