Answer to question 1
The normative sample can be described as the test takers who had been included in the sample. In this case they are 35,302 in number. SE, on the other hand, is inherently the measure of the statistical estimate which in this case is the RPR. The samples that were taken included persons who were not on current medication and also those ones who were on medication that could not affect RPR. Some of the factors that have to be controlled are age, race and ethnicity. The overall mean for the adult males is 71 beats per minute whereas that for adult females is 74 beats per minute (Ostchega et al., 2011).

Answer to question 2
Pulse rates for various United States males basing on age is what the graph in Figure 1 is measuring. From the figure, it is imperatively evident that the range of average RPRs across the four age groups that have been presented are similar. In addition to that, there is no significant statistical trend in the four groups (Ostchega et al., 2011).

Answer to question 3
From figure 4C, it is justified that the pulse rates are being normally approximated. That is due to the fact that other than the presence of a few outliers on the both the left and right hand sides of the curve; the curve also appears as if it has narrowed the distribution as age increases by progressing from platykurtic to a leptokurtic in terms of shape (Ostchega et al., 2011).

Answer to question 4
The resting pulse rate at the 50th percentile is 74 from table 3 (Ostchega et al., 2011).

Answer to question 5
This study has provided an overview of the normative data on RPR from a large population sample that was obtained lately. The results of the study have shown that RPR decreases with increase in age of both males and females. It is also justified that the average RPR for females was higher than that of males with exceptions of persons who were over 80 years old. Hence, the difference can be used to provide come up with suitable clinical guidelines for the two groups (Ostchega et al., 2011).
