Afina-wow [57]

Answer:

So, the interquartile range is IQR=22.5.

Step-by-step explanation:

Let us write the numbers in ascending order:

34, 37, 38, 40, 44, | 46, 50, 51, 55, 56, |

57, 61, 62, 65, 65, | 68, 68, 72, 73, 76.

We calculate quartile 1:

$Q_1=\frac{44+46}{2}=45$

We calculate quartile 2:

$Q_2=\frac{56+57}{2}=56.5\\$

We calculate quartile 3:

$Q_3=\frac{65+68}{2}=67.5\\$

We calculate the interquartile range:

$IQR=Q_3-Q_1\\\\IQR=67.5-45\\\\IQR=22.5$
