Answer #1

= (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
