Answer:

Please find attached the required box and whiskers plot

Explanation:

The numbers are given in arranged order as follows;

14, 14, 16, 16, 17, 17, 18, 20, 21, 23

The five number summary are;

The minimum value = 14

The maximum value = 23

The first quartile, Q₁, is the (n + 1)/4th term or the 2.75th term = 14 + 0.75×(16 - 14) = 15.5

The second quartile, Q₂, (the median) is the (n + 1)/2th term or the 5.5th term = 17

The third quartile, Q₃, is the 3(n + 1)/4th term or the 8.25th term = 20 + 0.25×(21 - 20) = 20.25.
