Question: Accuracy of Children’s Systolic Blood Pressure Obtained with a Dinamap Monitor

In paper "Accuracy of Blood Pressure Measurement by the Dinamap Monitor in Infants in Children" in the Pediatrics (1987), Park & Menard present the results of a study comparing direct and Dinamap measured systolic blood pressures in children. Is there evidence based on the data collected that the two methods of measuring systolic blood pressure differ?

  1. What parametric test could be used to analyze these data? Are there any problems with the assumptions required for this analysis? Explain. (3 pts.)
  2. How could the binomial distribution be used to test for differences in mean systolic BP when using these two methods on the same patient? Explain and then conduct the test. (4 pts.)
  3. Use an appropriate nonparametric inferential procedure to answer this question and summarize your findings. (4 pts.)

The data from the study are presented below.
