Reference no: EM13933439

An experiment was conducted to compare the reaction times of a group of 10 volunteers (from a psychology class) to a bright light versus the sound of a loud air horn. When signaled with either the light or horn, the individual was asked to press a button to turn off the light or to turn off the horn. A special timing device monitored the reaction times (expressed in seconds):

Subject	Light(X)	Horn(Y )
1	0.31	0.29
2	0.37	0.30
3	0.41	0.38
4	0.33	0.35
5	0.21	0.25
6	0.38	0.29
7	0.38	0.31
8	0.47	0.37
9	0.95	0.21
10	0.25	0.22
