Problem (3)-.To determine whether glaucoma affects the corneal thickness, measurements were made in 8 people affected by glaucoma in one eye but not in the other. The corneal thickness (in microns) were as follows: Person Eye affected 488 478 480 426 440 410 458 460 Eye not affected 484 478 492 444 436 398464 476 4 (a) According to the data, can you conclude, at the significance level of 0.10, that the corneal thickness is not equal for affected versus unaffected eyes? Please write the entire R code to check the assumptions necessary and to perform the test. (b) Calculate a 90% confidence interval for the mean difference in thickness
