High levels of cockpit noise in an aircraft can damage the hearing of pilots who are exposed to this hazard for many hours. Cockpitnoise in a jet aircraft is mostly due to airflow at hundreds of miles per hour. This 3 x 3 contingency table shows 61 observations of datacollected by an airline pilot using a handheld sound meter in a certain aircraft cockpit. Noise level is defined as "low" (under 88decibels), "medium" (88 to 91 decibels), or "high" (92 decibels or more). There are three flight phases (climb, cruise, descent).Noise LevelLow (L)Medium (M)High (H)Column TotalCockpit Noisei P(B)ii P(L)iii P(H|C)iv P(HID)v P(L and B)vi P(L and C)Climb(B)717630Flight PhaseCruise Descent(C)(D)67332111020Click here for the Excel Data File(a) Calculate the following probabilities: (Round your answers to 4 decimal places.)0.4918Row Total20231861
