We have been given that the standard deviation of a group of 20 scores is 15 and we are asked to find variance.
Since we know variance is square of standard deviation. In order to find out the variance of the given data we have to take the square of 15.
Therefore, our variance is 225.
You can solve this by dividing 27 people by 4 groups:
27/4
4 goes into 27 [6] times
6 *4=24
27-24=3
There will be 3 remaining.
If you have any questions or want me to explain it another way, let me know :)
Step-by-step explanation:
This is the answer of this question.
? + 8 = 11
Subtract 8 from both sides.
? = 3
HG = 8
? + 6 = 9
Subtract 6 from both sides.
? = 3
HI = 3
