Graph description: Figure 7. Normal plot for the birthweight data, births at or above 37 weeks gestation only

Two graphs: a histogram and a Normal plot.

The histogram of birth weight is symmetrical. A Normal curve is superimposed which fits the histogram very closely.

The Normal plot shows Inverse Normal on the horizontal axis and birthweight on the vertical axis. The points are very close to the straight line, which they completely obscure.
