Your answer
Transcribed Image Text:10. The paper "The Variability of Blood Pressure Measurements in Children" (Amer.
J. of Public Health (1983): 1207-11) reported the results of a study of 99 third-
grade children. The sample consisted of 53 boys and 46 girls. The values of several
variables, including systolic blood pressure, diastolic blood pressure were recorded
for each child. Means and standard deviations are given in the accompanying
table.
