The heights of 50 students, measured to the nearest centimetres, have  been found to be as follows: 161 150 154 165 168 161 154 162 150 151162 164 171 165 158 154 156 172 160 170153 159 161 170 162 165 166 168 165 164154 152 153 156 158 162 160 161 173 166161 159 162 167 168 159 158 153 154 159 (i) Represent the data given above by a grouped frequency distribution table, taking the class intervals as 160 - 165, 165 - 170, etc.(ii) What can you conclude about their heights from the table?

Explanation

To solve the problem step by step, we will first create a grouped frequency distribution table for the heights of the 50 students.

### Step 1: Organize the Data
We have the heights of 50 students. The heights range from 150 cm to 173 cm. We will create class intervals of 5 cm each, starting from 150 cm.

### Step 2: Define Class Intervals
The class intervals will be:
- 150 - 155
