Weights for a certain species of newt are normally distributed with a mean of 39 grams and standard deviation 9 grams.

The bell curve below represents the probability distribution for newt weights. The scale on the horizontal axis is equal to the standard deviation. Fill in the three indicated boxes. Note that the two outside boxes are 2 standard deviations from the mean.
