The table below displays the diagnoses of multiple sclerosis for two neurologists. The categories are (1) Certain multiple sclerosis, (2) probable multiple sclerosis, (3) possible multiple sclerosis, and (4) doubtful, unlikely or definitely not multiple sclerosis. (Note that the last category was created by collapsing 3 categories). The first number in each cell is the observed cell count while the second number is the number that would be expected (to three decimal places) under independence. (The expected count for the first cell is missing.)

Question
100%
The Kappa statistic is calculated as 0.2001, indicating a fairly low level of agreement between the neurologists, and has an asymptotic standard error of 0.0516. SAS a 95% computes the confidence interval for the kappa to be (0.0990, XXXX). What should the upper endpoint be? Calculate the answer to four decimal places.
