Doing it on the other side. One standard deviation below the mean is 8.4. Two standard deviations below the mean. Subtract 1.1 again would be 7.3. And then three standard deviations below the mean, maybe right there, would be 6.2 kilograms. So that's our setup for the problem. So what's the probability that we would find a one-year-old girl in the US that weighs less than 8.4 kilograms?
