See the step by step solution

## Step  1 Given Information

We have to find the df for the numerator

## Step 2 Explanation

Use the table given below of weight for the different groups to calculate the degree of freedom for the numerator

## Step 3: Calculation

To calculate the degree of freedom for the numerator, use Ti-83 calculator. For this, click on STAT $\to$ press $1\to$ EDIT, then put the above-given weights of different groups' data into the list $L1$, $L2$ and $L3$. The screenshot is given below:

## Step 4 Calculation -2
