A study is conducted comparing three different prenatal care programs among women at high risk for preterm delivery. The programs differ in intensity of medical interventions. Women who meet the criteria for high risk of preterm delivery are asked to participate in the study and are randomly assigned to one of the three prenatal care programs. At the time of delivery, they are classified as preterm or term delivery. Based on the following data, is there a relationship between the prenatal care programs and preterm delivery?

Use the following data to run the appropriate test (by hand) at the 5% level of significance.

	Program 1: Minimal Intensity	Program 2: Moderate Intensity	Program 3: High Intensity
Preterm	34	18	12
Term	36	52	58
