Rates: 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 (i.e., the ANOVA Table) shown below. Use a 0.05 significance level to test the claim that the different hospitals have different mean birth weights. 1. compare the p value to the significance level, how do they compare? 2. Do the different hospitals have different mean birth weigjts? Why or why not? 3. Do birth weights appear to be different in urban and rural areas? Why do you think so?
