Answer:

MARK ME BRAINLIEST

Sure, Let's create a frequency distribution for the IQ data of the 40 children in the school. We'll use the following class intervals:

1. < 90

2. 90-110

3. 110-120

4. ≥ 120

Now, we'll count how many children fall into each interval. Let's say we have the following counts:

1. < 90: 5 children

2. 90-110: 15 children

3. 110-120: 10 children

4. ≥ 120: 10 children

So, the frequency distribution for the IQ data would look like this:

1. < 90: 5

2. 90-110: 15

3. 110-120: 10

4. ≥ 120: 10

I hope this helps! Let me know if you have any other questions.
