Suppose the operating costs of an MD-80 jet airliner are normally distributed with a standard deviation of $175 per hour. At what operating cost would only 20% of the operating costs be less?

6.57)(i) for 20 percentile ; zscore =-0.8416
therefore lowest 20% ; or only 20% of the operating cost be less =mean+z*std deviation=$1939.72
(ii) or 65% highest cost; at 35th percentile ; z =-0.3853
corresponding cost ==mean+z*std deviation= $2019.57
(iii)for 85th pecentile ; z =1.0364
corresponding cost ==mean+z*std deviation=$2268.38
