Question

Reaction distances in centimeters for a random sample of 40 college students were obtained. Shorter distances indicate quicker reactions. Each student tried the experiment both with his or her dominant hand, and with his or her nondominant hand, catching the meter stick. The subjects all started with their dominant hand.
Examine summary statistics, and explain what we can learn from them. Then do an appropriate test to see whether the mean reaction distance is shorter for the dominant hand. Use a significance level of 0.05.
