The data collected by Emily shows a clear trend that supports her hypothesis. As the rate of stirring increases (from no stirring to slow stirring to fast stirring), the time required for the antacid to dissolve decreases significantly (220 seconds for no stirring, 80 seconds for slow stirring, and 45 seconds for fast stirring).
Based on this consideration, the appropriate conclusion is:
B. The data supports the hypothesis.
