heres the question

a. Are there any statistically signicant differences in the characteristics shown among the treatments? Justify your answer. b. Consider the test for differences in age among treatments. Write the hypotheses and the formula of the test statistic used (No computations required formula only). 0. Consider the test for differences in insurance coverage among treatments. Write the hypotheses and the formula of the test statistic used (No computations required formula only). d. Consider the test for differences in disease stage among treatments. Write the hypotheses and the formula of the test statistic used (No computations required formula only). The following data were collected in an experiment designed to investigate the impact of different positions 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 assigned to one position and have the fetal heart rate measured in that position. Each woman is between 28-32 weeks gestation. The data are shown below. Mean: 142.0 Mean- 141.8 Mean- 145. 6 Mean =1.46 8 Is there a significant difference in mean fetal heart rates by position? Run the test at a 5% level of significance
