Exercise 1
Answer A
Lower limit = 27.94 kg/m^2 - 4.85 kg/m^2 = 23.09 kg/m^2
Upper limit = 27.94 kg/m^2 + 4.85 kg/m^2 = 32.79 kg/m^2
Answer B
Lower limit: µ - 2σ
Upper limit: µ + 2σ
Lower limit = 27.94 kg/m^2 - 2 * 4.85 kg/m^2 = 27.94 kg/m^2 - 9.7 kg/m^2 = 18.24 kg/m^2
Upper limit = 27.94 kg/m^2 + 2 * 4.85 kg/m^2 = 27.94 kg/m^2 + 9.7 kg/m^2 = 37.64 kg/m^2
Answer C
Lower limit: µ - 3&sigma…
