Question

Please help me with the following question.

Answer 1

Explanation:

a . median (Q2) =

`(1(n + 1))/(2)`

`(1(31 + 1))/(2)`

`(32)/(2) = 6`

therefore the position of the media is the 6th term

6th term =3,11

b. first quartile(Q1)=

`(1(n + 1))/(4)`

`(1(31+ 1))/(4)`

`(32)/(4) = 8`

8th term= 2,56

C. third quartile(Q3)=

`(3(n + 1))/(4)`

`(3(31+ 1))/(4)`

`(96)/(4) = 24`

24th term = 3,85

D. IQR = Q3 - Q1

= 3,85 - 2,56

= 1,29

e.

`fi = 2.56 - 1.5 * 1.29`

`fi = 0.625`

`fu = 3.85 + 1.5 * 1.29`

`fu = 5.785`
