In a May 2011 study, Federal University Hospital in São Paulo, Brazil, 71 healthy pregnant women were separated into a control group and an experimental group. Those in the experimental group engaged in aerobic water exercise throughout their pregnancy whereas those women in the control group did not. After giving birth the neonatal outcome of the children of all women in the study was recorded where a negative neonatal outcome was defined as a hospital stay of more than four days. A set of similar results is shown in the table Group Positive Neonatal Outcome Negative Neonatal Outcome Water Exercise 15 15 Control Group 12 18 A hypothesis test was carried out, yielding a p-value of 0.396. What is the correct interpretation? 1.Do not reject H0 since the p-value is greater than 0.05. 2. Reject H0 since the p-value is greater than 0.05. 3. Do not reject H0 since the p-value is less than 0.05. 4. Reject H0 since the p-value is less than 0.05. AND Based upon this, provide an informative interpretation: 1. Neonatal outcome is significantly dependent on group assignment. 2. Neonatal outcome is not significantly dependent on group assignment. 3. There is a significant linear relationship between neonatal outcome and group assignment. 4. There is not a significant linear relationship between neonatal outcome and group assignment.
