This is a line graph. The horizontal axis shows the Allocation ratio, labeled 1, 2, 3, 4, 5. The vertical axis shows the Total sample size, labeled 0, 500, 1000, 1500, 2000. A single line starts at allocation ratio = 1, sample size size = 1000, and rise slowly and then more steeply to allocation ratio = 5, sample size = 1800.
