Question

What are the minimum, first quartile, 20 70 13 15 23 17 40 51

Answer 1

Answer:

Minimum 13

First quartile 16

Step-by-step explanation:

Rewrite the sample 20 70 13 15 23 17 40 51 in ascending order:

13  15  17  20  23  40  51  70

The minimum is 13.

The median is the middle number

13  15  17  20  23  40  51  70

The middle number between 20 and 23 is

$\dfrac{20+23}{2}=21.5$

Consider first half of the sample

13  15  17  20

The first quartile is the middle number of this part. The middle number of

13  15  17  20

is

$\dfrac{15+17}{2}=16$
