The dot plot below shows the amount of time two random groups of students took to brush their teeth:
A dot plot shows Tooth Brushing Time in seconds on the horizontal axis. For Group R, there is 1 dot on 45, 2 dots on 50, 1 dot on 55, 2 dots on 60, 1 dot on 65, 1 dot on 70, 1 dot on 75, 1 dot on 80, 1 dot on 85, 2 dots on 90, 1 dot on 95, 2 dots on 100, 1 dot on 105, 2 dots on 110, 1 dot on 115, and 2 dots on 120. For Group S, there is 1 dot on 50, 1 dot on 55, 2 dots on 60, 2 dots on 70, 1 dot on 80, 2 dots on 90, 1 dot on 95, 1 dot on 100, 1 dot on 105, 2 dots on 110, 1 dot on 115, and 1 dot on 120.

Based on visual inspection of the dot plots, which of the following groups, if any, shows a greater average time required to brush their teeth? Group R Group S Both groups show about the same average time. No conclusion about average time can be made from the data.

Answer 1

Well it's hard to visually inspect this long text; let's look at it.

$\begin{matrix} \textrm{Secs} & \textrm{GroupR} & \textrm{GroupS} \\ 45 & 1 & 0 \\ 50 & 2 & 1 \\ 55 & 1 & 1 \\ 60 & 2 & 2 \\ 65 & 1 & 0\\ 70 & 1 & 2 \\ 75 & 1 & 0 \\ 80 & 1 & 1 \\ 85 & 1 & 0 \\ 90 & 2 & 2 \\ 95 & 1 & 1 \\ 100 & 2 & 1 \\ 105 & 1 & 1 \\ 110 & 2 & 2 \\ 115 & 1 & 1 \\ 120 & 2 & 1 \\ \end{matrix}$

Based on visual inspection the averages look about the same.
