Question

A researcher measured the time (in seconds) required to catch a falling meter stick for 12 randomly selected students' dominant and non-dominant hand. The researcher claimed that the reaction time in an individual's dominant hand is less than the reaction time in their non-dominant hand. The data appear below

	Dominant	Non-Dominant	Difference
Sample Size	12	12	12
Sample Average	0.1798	0.1929	-0.0131
Sample Standard Deviation	0.01752	0.01799	0.01643

Is there sufficient evidence at the alpha = .05 level of significance to confirm the researcher's? What is the P-value of your test statistic?
