In a May 2011 study, Federal University Hospital in São Paulo, Brazil, 82 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 Water Exercise Control Group Positive Neonatal Outcome Negative Neonatal Outcome 21 17 19 25 Source: UPECLIN HC FM Botucatu Unesp At a 5% level of significance, test the claim that the neonatal outcome was unrelated to the group in which they were assigned. (Water exercise or control group.) Step 3: Calculate the test statistic. Round the value to three decimal places. Answer:x² = Number Hint: RStudio can calculate test statistics from a table using the command chisq.test (table, correct=FALSE) In a May 2011 study, Federal University Hospital in São Paulo, Brazil, 82 healthy pregnant women were separated into a control group and an experimental group.
