An aircraft emergency locator transmitter (ELT) is a device designed to transmit a signal in the case of a crash. Suppose that the Bryant Company makes 32% of ELTs; the rest are made by the Altigauge Manufacturing Company. If an ELT is made by the Altiguage Manufacturing Company, there is a 9.1% chance it is defective. If an ELT is made by the Bryant Company, there is a 93.1% chance it is non-defective. Use this information to answer the following questions. a. Complete the following contingency table. Please enter your answers as probabilities, not percentages or counts. Do NOT round any values in the table! Note: you must complete at least the table to receive any marks on this question.
