Answer
The data suggest that younger internet users (age group A) are more likely to use the internet for storing files compared to older internet users (age group D). This trend indicates that internet usage for storing files may decrease with age, showing a correlation between age and technology adoption.

Answer
To graphically display the percentages for 2014 and 2015, a bar chart can be used. Each age group (A, B, C, D) should have two bars: one for 2014 and one for 2015. Ensure the y-axis represents the percentage values and the x-axis represents the age groups. Label the bars accordingly.
