The data in Table 7–7 are collected in an experiment designed to investigate the impact of different posi- tions of the mother during ultrasound on fetal heart rate. Fetal heart rate is measured by ultrasound in beats per minute. The study includes 20 women who are each assigned to one position and have the fetal heart rate measured in that position. Each woman is between 28 weeks and 32 weeks gestation. Is there a significant difference in mean fetal heart rates by po- sition? Run the test at a 5% level of significance.
