Question

For an \(F\)-curve with \(df=(20,21), find

a. \(F_{0.01}\)

b. \(F_{0.05}\)

c. \(F_{0.10}\)

Short answer

Part a. The value of \(F_{0.01}\) is \(2.87956\) and the graph is shown in Figure 1.

Part b. The value of \(F_{0.05}\) is \(2.09603\) and the graph is shown in Figure 1.

Part c. The value of \(F_{0.10}\) is \(1.77555\) and the graph is shown in Figure 1.

Step-by-step solution

Part a. Step 1. Given information

The degree of freedom of the \(F-\)curve is \(df=(20,21)\)

Part a. Step 2. Calculation

From the table, for \(df=(20,21), F_{0.01}=2.87956\).

The graph of the F-curve is shown in the figure below:

Part b. Step 1. Calculation

From the table, for \(df=(20,21), F_{0.05}=2.09603\).

The graph of the F-curve is shown in the figure below:

Part c. Step 1. Calculation

From the table, for \(df=(20,21), F_{0.10}=1.77555\).

The graph of the F-curve is shown in the figure below:
