Early Preterm Late Preterm Most pregnancies are full term, but some are preterm (less than 37 weeks). Of those that are preterm, they are classified as early (less than 34 weeks) and late (34 to 36 weeks). A report examined those outcomes for one year, broken down by Under 20 age of the mother. Is there evidence that the outcomes are not independent of age group? 129 272 20 to 29 30 to 39 243 162 19 604 429 42 40 or Over ...

can you help with x^2 statistic? As well as P-value and then check the others? 

Most pregnancies are full term, but some are preterm (less than 37 weeks). Of those that are preterm, they are classified as early (less than 34 weeks) and late (34 to 36 weeks).
