Homework Answers
= (554+ 577+498+.....+499) /15
= $ 533
number of observation = 15
median is the 8th oobservation after arranging the data in ascending order
median = $534
=[(554-533)2
+.....+(499-533)2]/14= 1042.143
Standard deviation = square root of variance = $32.28
coefficient of skewness = (mean -median )/ Standard deviation = -0.031
