As people age they begin to experience hearing loss. A study was done to determine the 'comfort level' of sound for people of different ages. The data are given below: Age (years) Comfort Level (decibels) 15 25 35 45 55 65 75 85 56 57 64 64 68 74 78 85 Note: Σx 400 , Σy-546 , Σ- 4200, ΣΥ-37986, Σw-290 10 %3D a) Calculate the linear correlatiof coefficient, r. b) Calculate the line-of-best-fit (linear prediction line.) c) If a person is 60 years of age, what do you predict the 'comfort level’ of sound would
