Answer 1

a) the mean =56.32

the median =55.37

b)variance =379.78

standard deviation =19.49

range =85.55

Coefficient of variation =(std deviation/mean)*100 =(19.49/56.32)*100 =34.61% (try 34.60% if this comes wrong)

c)

yes the data are right skewed

d)

the average amount spent is 56.32 and half the customer spent more than 55.37 . the average scatter,,,,,mean is 19.49 . The difference between...........spent is 85.55
