Expert Solution

We will arrange the numbers in increasing order first

4,5,6,10,19,21,26,27,51,101,119,212,525

Total 13 numbers are there

  • Mean = Sum of number set / Total numbers

Mean =(4+5+6+10+19+21+26+27+51+101+119+212+525)/13

Mean = $ 86.6

  • Meadian is the number in the middle when the number set in ascending order

Meadian = $ 26

  • Mode is the number that is repeated more often than any other

Mode = none here

  • Range =Largest value-Smallest value

Range = 525-4 =521

Range is $ 521

  • Midrange = (Maximum value + Minimum value)/2

Midrange =(525+4)/2 = 264.5

Midrange is $ 264.5

  • Standared deviation =

=86.6

Standared deviation is $139.3
