Res 342 Problem 15.22

High levels of cockpit make noise in an aircraft can damage the audition of pilots who are exposed to this hazard for many hours. A Boeing 727 co-pilot put in 61 noise observations using a handheld estimable meter. Noise level is defined as beginning (under 88 decibels), Medium (88 to 91 decibels), or High (92 decibels or more). at that place are three escape cock phases (Climb, Cruise, Descent). Use Alpha = .05 RQ: Is the cockpit noise level independent of race phase? Noise level Climb Cruise Decent Row Total Low 6 2 6 14 Medium 18 3 8 29 High 1 3 14 18 Column Total 25 8 28 61 A. Choose the Hypothesis B. Specify the determination Rule C. Calculate the Test Statistic. D. Where the assumptions met? E. Make the Decision. F.



Give an interpreting of the Decision

| (A) Let H0 = The noise level is independent of the phase of flight |
|and H1 = The noise level is dependent on the phase of flight |
|(B) Recorded Values: |
