Question

You weigh six packages and find the weights to be 19, 15, 35, 17, 33, and 31 ounces. If you include a package that weighs 39 ounces, which will increase more, the median or the mean?

Answer 1

Explanation:

Mean & median of 6 packages:

15, 17, 19, 31, 33 , 35

Median =
`(19+31)/(2)`

=
`(50)/(2)`

= 25

`Mean = (15+17+19+31+33+35)/(6)\\\\=(150)/(6)\\=25`

Mean & median of 7 packages:

15,17,19,31,33,35,39

Median = 31

`Mean=(19+15+35+17+33+31+39)/(7)\\\\=(189)/(7)\\\\=27`

After including 39 ounce package, Median will increase more
