Anew radar device is being considered for a certain missile defense system. the system is checked by experimenting with aircraft in which a kill or a no kill is simulated. two research group a and b participated the simulation, and it was found that 63 kills occur out of 100 trials by group a, and 59 kills occur out of 125 trials by group b. is there a significant difference between the proportions of group a and b's simulation? use p-value with significance level of 0.05 to draw a conclusion.
