$df=$___

Short answer

The degree of freedom $df$ is $4$.

Step-by-step solution

Step 1. Given information

The given table as shown below:

	$20-30$	$30-40$	$40-50$	$50-60$
Private Practice	16	40	38	6

Private Practice	16	40	38	6
Hospital	8	44	59	39

The formula to calculate the degree of freedom is $df=$ number of column $-1$ .

Here, the number of column is $5$ .

$df=numberofcolumn-1$

$=5-1$

$=4$

The degree of freedom $df$ is $4$.
