3. From a laboratory study of nine independent lives: (i) The time-until-death of each life, in years, is: 1, 2, 4, 5, 5, 7, 8, 9, 9. (ii) It is hypothesized that the time-until-death for a life has a uniform distribution on the interval (0, 11). (iii) The critical value to be used for the Kolmogorov-Smirnov goodness- of-fit test at a significance level of 5% is 1.36 7, where n denotes the sample size. Determine the result of the Kolmogorov-Smirnov goodness-of-fit test to test that the time-until-death for a life has the hypothesized uniform distribution at a significance level of 5%.\f1. D) There should be complete compliance with the treatment protocol is one condition that must not be satisfied such that the instrumental variable used in a quasi-experiment is a valid instrument for the treatment actually recieved. 2. Studies that expolit a discountinuity in the probability of recieving treatment at threshold value are called regression discountinuity designs. 3. The statement that are true about Regression discountinuity designs are: bj In a FRDD, crossing the threshold influences receipt of the treatment but is not the sole determinant of whether the treatment is recieved or not. () In SRDD, receipt of treatment is entirely determined by whether the forcing variables exceeds the threshold or not
