Cockpit noise in a jet aircraft is mostly due to airflow at hundreds of miles per hour. This 3 × 3 contingency table shows 61 observations of data collected by an airline pilot using a handheld sound meter in a certain aircraft cockpit. Noise level is defined as "low" (under 88 2 decibels), "medium" (88 to 91 decibels), or "high" (92 decibels or more). There are three flight phases (climb, cruise, descent). points Cockpit Noise Flight Phase Noise Level Climb (B) Cruise (C) Descent (D) Row Total LOW ( L ) 6 14 Book Medium (M) 8 29 1 00 / W W N High (H) 14 18 Column Total 28 61 References Click here for the Excel Data File (a) Calculate the following probabilities: (Round your answers to 4 decimal places.) i .
