I am so confused with what my teacher told me to do. I have this graph that I made.

I will have to look..i was looking to see a graph that shows the difference in the height from one age to the other age group based on the current age.

Does this make sense?

In other words for an 80-year-old..what is the height difference for this person?

What does she mean by that? it\'s so confusing for me. please help me out. I believe I already have on my graph what she\'s talking about but she said it\'s still lacking. I already indicated by the different colors on the graph of the current age what was the height difference.

Change in Height in Senior Citizens (White Female) 8.3 8.5 7.5 -6.5 5.4 5.5 2 4.5 4 3.7 3.5 2.7 2.5 1.5 0.8 0.5 0 80 83 72 72 CURRENT AGE Age 40-Age 50 ·Age 40-Age 60 Age 40-Age 70

Solution

Basically you have to make a graph that shows difference in height of the three groups at current age.

You haven\'t given detail about source data from which you created this graph.
I think you messed few things like look at the groups you used
(Age 40-50)
(Age 40-60)
(Age 40-70)

According to me it should be
(Age 40-50)
(Age 50-60)
(Age 60-70)

If you can provide source data also the exact instruction that your teacher said then I can explain in more detail.
