Athletes performing in bright sunlight often smear black eye grease under their eyes to reduce glare. Does eye grease work? In one study, 16 student subjects took a test of sensitivity to contrast after three hours facing into bright sun, both with and without eye grease. (Greater sensitivity to contrast improves vision, and glare reduces sensitivity to contrast.) This is a matched pairs design. The differences in sensitivity, with eye grease minus without eye grease, are given in the table. 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 Click to download the data in your preferred format. CSV Excel JMP Mac-Text Minitab14-18 Minitab18+ PC-Text R SPSS TI CrunchIt! How much more sensitive to contrast are athletes with eye grease than without eye grease? Give a 95% confidence interval to answer this question. Give your answers to four decimal places.
