Answer:
Option C
Explanation:
Given the data set, 23, 32, 20, 13, 27, 36, 29, 38, 23, 15, 30, 18, to find out which box-and-whisker plot matches the data, let's work out the 5-number summary needed for constructing a box plot.
The five-number summary includes the min, Q1, median, Q3 and max value.
Let's find them.
First, order the data set from the least to the largest
13, 15, 18, 20, 23, 23, 27, 29, 30, 32, 36, 38
Min = 13
Max = 38
Median = (23 + 27) ÷ 2 = 50 ÷ 2 = 25
Q1 = (18 + 20) ÷ 2 = 38 ÷ 2 = 19
Q3 = (30 + 32) ÷ 2 = 62 ÷ 2 = 31
The box-and-whiskers plot will have the description given in option C.
