Transcribed Image Text:Glaucoma is a leading cause of blindness in a country. An ophthalmologist measured the corneal thickness of eight patients who had glaucoma in one eye but not in the other. The data on corneal
thickness, in microns, are shown in the accompanying table. Preliminary data analyses indicate that use of a paired t-test is reasonable. At the 5% significance level, do the data provide sufficient
evidence to conclude that mean corneal thickness is greater in normal eyes than in eyes with glaucoma? Use the critical-value approach.

What are the hypotheses for the t-test? Let population 1 be corneal thickness in normal eyes and let population 2 be corneal thickness in eyes with glaucoma.
