A study is being made of the failures of an electronic component. There are four types of failures possible and two mounting positions for the device. The following data have been taken: Failure Type Mounting Position A B C D 1 22 46 18 9 2 4 17 6 12 Would you conclude that the type of failure is independent of the mounting position? Use a = 0.01. (a) Calculate the test statistic x. Round your answer to two decimal places (e.g. 98.76). i (b) Is failure type independent of mounting position?
