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 (f) Fit a normal distribution to the data on eye not affected by glaucoma and com- ment on the adequacy of its fit. [1] (g) Construct a 95% confidence interval for the difference between the population mean of the data on eye affected by glaucoma and the population mean of the data on eye not affected by glaucoma. You may assume that the sample stan- dard deviations computed in parts (a) and (b) are the true population standard deviations. Comment on the confidence interval. Does the confidence interval suggest that glaucoma affects the corneal thickness? [2] (h) Let ux = the population mean of the data on eye affected by glaucoma and my = the population mean of the data on eye not affected by glaucoma. Test the hypothesis Ho : ux = muy versus H1 : ux
