In Exercises 5–16, use analysis of variance for the indicated test.

Birth Weights Data Set 4 “Births” in Appendix B lists birth weights from babies born at Albany Medical Center, Bellevue Hospital in New York City, Olean General Hospital, and Strong Memorial Hospital in Rochester, New York. After partitioning the birth weights according to the hospital, we get the StatCrunch display shown here. Use a 0.05 significance level to test the claim that the different hospitals have different mean birth weights. Do birth weights appear to be different in urban and rural areas?
