Low Birth Weight The University of Maryland Medical Center considers “low birth weights” to be those less than 5.5 lb or 2495 g. Birth weights are normally distributed with a mean of 3152.0 g and a standard deviation of 693.4 g (based on Data Set 3 “Births” in Appendix B).

a. If a birth weight is randomly selected, what is the probability that it is a “low birth weight”?

b. Find the weights considered to be significantly low using the criterion of a probability of 0.05 or less. How do these results compare to the criterion of 2495 g?

c. Compare the results from parts

(a) and (b).
