We have collected the following 50 observations on the time between call center calls in minutes We wish to test that this data comes from a normal distribution with mean 3 and variance 1. We calculated the KS-test statistic as D_50 = 0.1558. Calculate an approximate P value for this test. Find a numerical approximation to the level alpha = 0.05 critical value a using Calculate the Adjusted Test Statistic and critical value from the Table 1A in Stephens (1974). What happens to D_n and the result of the test if the largest value is changed from 4.97 to 111?
