A new approach to prenatal care is proposed for pregnant women living in a rural community. The new program involves in-home visits during the course of pregnancy in addition to the usual or regularly scheduled visits. A pilot randomized trial with 15 pregnant women is designed to evaluate whether women who participate in the program deliver healthier babies than women receiving usual care. The outcome is the APGAR score measured 5 minutes after birth. Recall that APGAR scores range from 0 to 10 with scores of 7 or higher considered normal (healthy), 4-6 low and 0-3 critically low. The data are shown below. Usual Care 8 7 6 2 5 8 7 3 New Program 9 9 7 8 10 9 6 Is there statistical evidence of a difference in APGAR scores in women receiving the new and enhanced versus usual prenatal care? How you are going to prove this significance?
