Use the following to answer the questions below:

Students in a small statistics class were asked to count the number of scars both on their "dominant" hand (the one they use most often) and on their "off" hand. The summary statistics are provided. It is of interest to compare the average number of scars on the dominant and off hands.

 ​ n ​ s Dominant 25 1.92 2.326 Off 25 2.72 3.007 Difference (D - O) 25 -0.8 2.363

Boxplots of the raw data are provided. Would it be appropriate to use a t-distribution to construct a confidence interval for, or perform a test about, the difference in the mean number of scars on dominant and off hands? Specifically mention which boxplot(s) you are using to justify your answer.
