Considering the given box-and-whisker plot, it is found that 50% of the data values are between 16 and 72.

<h3>What does a box-and-whisker plot shows?</h3>

A box and whisker plot shows five things:

  • The minimum value.
  • The 25th percentile, which is the median of the bottom 50%.
  • The median, which splits the entire data-set into two halfs, the bottom 50% and the upper 50%.
  • The 75th percentile, which is the median of the upper 50%.
  • The maximum value.

From this plot, we have that:

  • The 25th percentile is of 16.
  • The 75th percentile is of 72.

Hence, 50% of the data values are between 16 and 72.

PLEASE HELP I WILL MARK YOU AS BRAINLEST

Answer:

(i) Five number summary: Minimum value = 1, Q_1=18,Median=18.5, Q_3=20.5, Maximum value = 26.

(ii) IQR = 2.5, upper fence = 24.25 and lower fence = 14.25.

(iii) 26 is an outlier of the data.

Step-by-step explanation:

The given data set is

19, 18, 23, 18, 18, 26, 19, 16, 20, 18, 17, 21

Arrange the data set in ascending order.

16, 17, 18, 18, 18, 18, 19, 19, 20, 21, 23, 26

Divide the data set in 4 equal parts.

(16, 17, 18), (18, 18, 18), (19, 19, 20), (21, 23, 26)

Minimum value = 16

Q_1=\frac{18+18}{2}=18

Median=Q_2=\frac{18+19}{2}=18.5

Q_3=\frac{20+21}{2}=20.5

Maximum value = 26

The inter quartile range (IQR) of the data is

IQR=Q_3-Q_1=20.5-18=2.5

Upper fence :

Q_3+1.5(IQR)=20.5+1.5(2.5)=24.25

Lower fence :

Q_1-1.5(IQR)=18-1.5(2.5)=14.25

If the any element of the data set lies out side the upper fence and lower fence, then it is called an outlier.

26 ∉ [14.25, 24.25]

Therefore, 26 is an outlier of the data.
