The dot plots show the weights of a random sample of fish from two lakes. Pick the statement that describes the variability of the samples.
The variability of the weights of the fish in Lake S is greater than the variability of the weights of the fish in Lake R.
The variability of the weights of the fish in the two lakes are about the same.
