Glaucoma is a leading cause of blindness in a country. Anophthalmologist measured the corneal thickness of eight patientswho had glaucoma in one eye but not in the other. The data oncorneal thickness, in microns, are shown in the accompanyingtable. Preliminary data analyses indicate that use of a pairedt-test is reasonable. At the 10% significance level, do the dataprovide sufficient evidence to conclude that mean corneal thicknessis greater in normal eyes than in eyes with glaucoma? Use thecritical-value approach.
