From a nationwide study, we know that the mean diastolic blood pressure is 64.9 mm gH for children aged 5- 6 years of age, and that the measurements are normally distributed. Blood pressure measurements were taken on 11 children aged 5-6 years living in a specific community to determine whether their living conditions resulted in a difference in mean blood pressure. For these children the average diastolic blood pressure was found to be 59.3 mm Hg with standard deviation 7.8...
