6. Baseball players may use eye black in an attempt to reduce glare from the sun. We want to test whether eye black increases eye sensitivity. 16 subjects were tested, both with and without eye black. Their differences in sensitivity (eye black - without eye black) were: 0.07 0.64 -0.12 -0.05 -0.18 0.14 -0.16 0.03 0.05 0.02 0.43 0.24 -0.11 0.28 0.05 0.29 Assume the distribution is Normal with o = 0.22. Does this give evidence that eye black increases sensitivity? Perform a hypothesis test
