Using the normal probability paper shown in Table 6–3, label the x axis with the class boundaries as shown and plot the percents.
Data from in Table 6-3
The frequency distribution of systolic blood pressures along with cumulative percents is given as follows:
Boundaries | Comulative |
98.5–104.5 | 12% |
104.5-119.5 | 43% |
119.5-134.5 | 79% |
134.5-149.5 | 92% |
149.5-164.5 | 98% |
164.5-179.5 | 100% |
A normal probability paper is considered. From the above data, the class boundaries are taken on x-axis and percents are taken on y-axis. The cumulative percents of the given data are plotted in the graph as follows:
From the above normal probability plot, we can observe that all cumulative percents are in straight line form.
From the above normal probability plot, we can observe that all cumulative percents are in straight line form.
