Please use R to solve questions d and e.


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 thicknesses (in microns) were as follows Person Eye affected by glaucoma Eye not affected by glaucoma 1 488 484 2 478 478 3 480 492 4 426 444 5 440 436 6 410 398 7 458 464 8 460 476 (d) Draw boxplots of the data on eye affected by glaucoma and the data on eye not affected by glaucoma. Plot them side by side and c0mment on how they compare. [1] (e) Fit a normal distribution to the data on eye affected by glaucoma. Comment on the adequacy of the t of the normal distribution. You may use the Kolmogorov Smirnov test by using the R command ks.test (x. "pnorm", mean. sd) where x contains the data, mean is the sample mean of the data, and sd is the sample standard deviation of the data. If the p-value returned by the command is above 0.05 you may consider the distribution as providing an adequate t. [1]
