  1. Suppose the researcher wants to see if data provide sufficient evidence to conclude that mean corneal thickness ofgreater for the normal eyes than the eyes with glaucoma. Are the two samples: corneal thickness in normal and glaucoma eyes are independent or dependent samples? Explain your answer.
  2. From the provided plots: (A), (B) and (C), clearly state which plot/plots you would use to check any assumptions.
  3. Do you see any serious violations of those assumptions? Explain your answer without simply saying yes or no.
  4. To answer researchers question, which output: output 1, output 2 , output 3, would you use?Output1
  5. Output 2
  6. Output 3
  7. Explain the reason for your choice of output
  8. What is the p value for the test (copy it from your choice of output)?
  9. Using the p value you derived in part 6, what would be your conclusion to the researchers question at 10% significance level.
