Answer:
Variance = 25
Step-by-step explanation:
<em>Standard deviation is the under root of variance.</em>
<em>Variance is the square of standard deviation.</em>
<u>Data:</u>
Mean = 70
Variance = ?
Standard deviation = √variance = 5
Variance = 5²
Variance = 25.
Therefore, the variance is 25.
One way to I solve this is by listing all the ways it can be multiplied by:
72: 1*72, 2*36, 3*24, 4*18, 6*12, 8*9.
80: 1*80, 2*40, 4*20, 5*16, 8*10.
Group the factors that they have in common.
Which are 1, 2, 4, and 8.
After that, find the greatest common factor that they both share.
Answer: 8
