An ecologist selected a random sample of 30 prairie dogs from a colony and found that the mean mass of the prairie dogs in the sample was 0.94 kg with an associated margin of error of 0.12 kg. which of the following is the best interpretation of the ecologist's findings?
a) all prairie dogs in the sample have a mass between 0.82 kg and 1.06 kg
b) most prairie dogs in the colony have a mass between 0.82 kg and 1.06 kg
c) any mass between 0.82 kg and 1.06 kg is a plausible value for the mean mass of the prairie dogs in the sample
d) any mass between 0.82 kg and 1.06 kg is a plausible value for the mean mass of the prairie dogs in the colony.
