A completely randomized design was conducted to compare the effects of five stimuli on reaction time. Twenty-seven people were employed in the experiment, which was conducted using a completely randomized design. Regardless of the results of the ANOVA, it is desired to compare stimuli A and D. The reaction times (in seconds) were as shown in the accompanying table.

	Stimulus
	A	B	C	D	E
	0.8	0.7	1.2	1	0.6
	0.6	0.8	1	0.9	0.4
	0.6	0.5	0.9	0.9	0.4
	0.5	0.5	1.2	1.1	0.7
		0.6	1.3	0.7	0.3
		0.9	0.8
		0.7
Total	2.5	4.7	6.4	4.6	2.4
Mean	0.625	0.671	1.067	0.92	0.48
