A cognitive psychology lab measures reaction times (in seconds) for six subjects responding to two different auditory cues. Each subject's reaction time to cue A and cue B is recorded as follows:
Table showing reaction times in seconds for six subjects responding to auditory cues A and B with paired data.
The sample standard deviation of these differences is 0.0210.021. Is the mean reaction time to cue A different from cue B at the α=0.01\(\alpha\)=0.01 level? Assume paired differences are approximately normal with no outliers.
