The mean birth weight of babies at University of Maryland Hospital is 3152.0 g with a standard deviation of 693.4 g.

Low birth weight babies need extra medical care, and the hospital does special screening on babies below the 15th percentile of weights. Below what weight should babies receive the extra screening?

For high birth weights, the hospital screens the mothers for gestational diabetes. What is the cut off weight for the top 10% of babies?

What percent of babies are less than 3000 g?

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
