Low Birth Weight The University of Maryland Medical Center considers “low birth weights” to be those that are 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 4 “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 birth weight having a probability of 0.05 or less. c. Compare the results from parts (a) and (b).

Question

Low Birth Weight The University of Maryland Medical Center considers “low birth weights” to be those that are 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 4 “Births” in Appendix B).
