AVERAGE OF DEATH IN PEOPLE WITH HIGH BLOOD PRESSURE 2
Introduction
The research question raised in this paper is “whether there is a difference in the average age at
death (AgeAtDeath) for those who had high blood pressure as compared to those who didn’t”.
The design of this study employed both the descriptive and hypotheses for the inferences and
assertions about the topic of the research. The study also employed quantitative analysis of the
data collected from the participants from the Framingham study which began in 1948. The
participants were adults were from Framingham (Massachusetts) which were recruited and
followed throughout their lives. A random sample of 500 participants who died during the course
of the study were the main suspect in the population and thus formed the basis of the research.
Exploratory data Analysis
Graphical Summary
For the visualization, the histograms below shows the distribution of the age at death for those
who had high blood pressure and those who didn’t. In relation to the exploratory variable on blood
pressure, anything beyond equal to or beyond 130 systolic BP is considered as high, Equal to 80 and above for
diastolic is high. Usually in patients with high blood pressure both would be high but one of them is enough to
diagnosis high blood pressure.

Summary Statistics
The summary statistics for the age at death for systolic and diastolic patients is presented in the
below.
N Minimum Maximum Mean
Diastolic 500 52.00 150.00 78.91
Systolic 500 98.00 286.00 144.74
Table 1: Summary Statistics
From the summary statistics, the average diastolic is 78.91 which is low while systolic average is
144.74 which is high.
In this work, two sample independent sample t-test would be used to determine whether the
means or average of the two groups are equal to each other.
