Consider the age distribution in the United States in the year 2075 (as projected by the Census Bureau).

Age Range Millions of People
0 - 9 34.9
10 - 19 35.7
20 - 29 36.8
30 - 39 38.1
40 - 49 37.8
50 - 59 37.5
60 - 69 34.5
70 - 79 27.2
80 - 89 18.8
90 - 99 7.7
100 - 109 1.7

Construct a cumulative frequency plot and describe what information the plot communicates about the distribution of ages in our future.

mhchen · Answer

First, find the frequency of each.

x/total

First: 34.9/total
Second: (34.9+35.7)/total

etc.

This is your y-axis.
The x-axis is the age-range bin.

Thank you, I understand how to create the graph I just don't understand how to describe the information the plot communicates.

retireed · Answer

Just eyeballing the data, I would say it looks like a fairly linear slope up the age of ______ ?  

You actually calculate the slope of the best fit line if you felt inclined.
