Side-by-Side -TP Athletes performing in bright sunlight often smear black with normal vision, that contrast differences follow a eye grease under their eyes to reduce glare. Does eye grease Normal distribution in this population, and that the standard work? In one study, 16 student subjects took a test of visual deviation of differences is o = 0.22. Carry out a test sensitivity to light-and-dark contrast after three hours facing of significance. into bright sun, both with and without eye grease. This is a matched pairs design. If eye grease is effective, subjects will be more sensitive to contrast when they use eye grease. The SOLVE: What is the value of the test statistic?
