Explanation

To solve the problem step by step, we will follow the instructions provided in the question.

### Step 1: Construct the Grouped Frequency Distribution Table

1. **Identify the Classes:**
The classes are given as 84-86, 86-88, etc. We will continue this pattern until we cover the maximum value in the data set.

The classes will be:
