Here it is given that - Mean (μ) = 2327 Standard deviation (σ) = 584.3a) 6th percentile = μ + zσ = 2327 + (-1.555*584.3) [ corresponding z value is -1.555] = 2327 - 908.5865 = 1418.4135 ≃ 1418 So, 1418 KWh consumption level represents 6th percentile. b) 17th percentile = μ + zσ = 2327 + (-0.954*584.3) [ corresponding z value is -0.954] = 2327 - 557.4222 = 1769.5778 ≃ 1770 So, 1770 KWh consumption level represents 17th percentile. c) Third quartile = 75th percentile 75th percentile = μ + zσ = 2327 + (0.674*584.3) [ corresponding z value is 0.674] = 2327 + 393.8182 = 2720.8182 ≃ 2721 So, 2721 KWh consumption level represents third quartile.
