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 10% 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. OA. Ho: H₁ H₂ H₂H₁ <H₂ OB. Ho H₁ H₂ H₂: H₁> H₂ ỌC. Ho. H=2 H₂: H₁> H₂ O D. H₂ H₁ H₂ H₂: H₁ H₂ Find the test statistic. (Round to two decimal places as needed.) Find the critical value(s). The critical value(s) is/are (Round to two decimal places as needed. Use a comma to separate answers as needed.) What is the conclusion for the hypothesis test? Ho the data ▼sufficient evidence at the 10% significance level that mean corneal thickness in normal eyes is that in eyes with glaucoma.
