To use appropriate visual tool and explain it.

Explanation of Solution

Given:

Fast	Slow
0.000101	0.000098
0.000102	0.000096
0.000100	0.000097
0.000102	0.000095
0.000101	0.000094
0.000103	0.000098
0.000104	0.000096
0.000102	0.975600
0.000102	0.000097
0.000100	0.000096

There is outlier value in data set Slow. The value is 0.975600 which violet the results. Therefore, first we remove that value and will construct boxplots for both data set.

  

The shape of the distributions of Fast speed and Slow speed are both skewed. The distance is greater for the fast speed, because the boxplot lies completely to the right of to the boxplot of the slow speed. The spread of the low speed is greater than the Fast speed. In the point of view of accuracy, Fast speed is better due to less spread.
