My Tutor has given me two notes on my work. Please finish exactly what she wants me to do.
I will write my teacher’s comments for you here below, and you will also find my teacher’s comments highlighted in yellow. I ask you to follow the instructions completely and correct what my teacher wants.
1. She said that I need to show the age ranges as percentages for departments C & D
2. She also asked me to present the data in two different formats (you have shown 2 bar charts) and then you need to explain any potential issues and recommended solutions for departments C and D. Thank you very much.
