Range=

Mode=

Data: -17.5, 2.8, 3.2, 25.3, 14.1, 45.8, 13.9

Please show the steps and label everything. Thank you!

Answer 1

Solution:

Given that,

The sample Mean is

=  x /n

= (17.5+ 2.8+ 3.2+ 25.3+ 14.1+ 45.8+13.9 / 7 )

= 122.6 / 7

= 17.5143

The sample Mean is 17.51

Median =  Data is ascending order is as below

2.8,3.2,13.9,14.1,17.5,25.3,45.8

n = 7

M = Value of ( n + 1 / 2 )^th observation

= Value of ( 7 + 1 / 2)^th observation

  = Value of 4 ^th observation

= 14.1

Median = 14.1

Range= Hieghest value - Lowest value

= 45 .8 - 2.8

= 43

Range = 43
