The data in Table 7–7 were collected in an experiment designed to investigate the impact of different positions of pregnant women on fetal heart rate. Fetal heart rate is measured by ultrasound in beats per minute. The study included 20 pregnant women who were assigned to one position and had the fetal heart rate measured in that position. Each woman was between 28 weeks and 32 weeks gestation. Is there a significant difference in mean fetal heart rates by position? Run the test at a 5% level of significance.
