The dot plot below shows the amount of time two random groups of students took to solve a math problem:
A dot plot shows Problem Solving Time in seconds on the horizontal axis. For Group X, there is 1 dot on 45, 2 dots on 50, 1 dot on 55, 1 dot on 60, 2 dots on 65, 3 dots on 70, 1 dot on 75, 1 dot on 80, 2 dots on 85, 3 dots on 90, 1 dot on 95, and 1 dot on 100. For Group Y, there are 2 dots on 65, 1 dot on 70, 1 dot on 75, 1 dot on 80, 2 dots on 85, 2 dots on 90, 1 dot on 95, 3 dots on 100, 1 dot on 105, 1 dot on 110, 3 dots on 115, and 1 dot on 120.
