Question

State the decision and conclusion (in a complete sentence) for the following preconceived levels of \(\alpha\).

\(df=\)___

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
Hospital	8	44	59	39

Step 2. Explanation

The given table as shown below:

	\(20-30\)	\(30-40\)	\(40-50\)	\(50-60\)
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 \(5\) .

\(df=number of column -1\)

\(=5-1\)

\(=4\)

The degree of freedom \(df\) is \(4\).
