Use the data to create a scatter plot.

time (years) number of participants
(x1000) 3 22 6 25 9 28 12 14 15 17 18 20 21 15 24 9

I'm not sure about the given data but I plotted the scatter plot based on what I understand on how the data should be presented.

Time (years)
3, 6, 9, 12, 15, 18, 21, 24

Number of participants(x1000)
22, 25, 28, 14, 17, 20,15, 9

Attached is the scatter plot created online.
x = time (years)
y = number of participants
