The mean response was 5.7 with a standard deviation of 2.2. (a) What response represents the 90th percentile? (b) What response represents the 63rd percentile? (o) What response represents the rst quartile? (a) The response that represents the 90th percentile is D. (Round to two decimal places as needed.) The per capita energy consumption level (in kilowatt-hours) in a certain country for a recent year can be approximated by a normal distribution, as shown in the figure. (a) What consumption level represents the 4th percentile? H = 2290 KWh 6 = 591.1 KWI (b) What consumption level represents the 20th percentile? (c) What consumption level represents the third quartile? X 290 2290 4290 Kilowatt-hours (a) The consumption level that represents the 4th percentile is kilowatt-hours. (Round to the nearest integer as needed.)
