QUESTION 1 The following data were collected in an experiment designed to investigate the impact of different positions of the mother on fetal heart rate. Fetal heart rate is measured by ultrasound in beats per minute. The study included 20 women who were assigned to one position and had the fetal heart rate measured in that position. Each woman was between 28-32 weeks gestation. The data are shown below. 2124 Back Side Sitting Standing 20 21 26 24 23 25 25 26 25 27 28 21 24 28 29 1916 24 25 Is there a significant difference in mean fetal heart rates by position?
