Answer:
4.6
Step-by-step explanation:
Allow me to revise your question and hope it will be the same as the original one:
In a certain town 22% of voters favor a given ballot measure for groups of 21 voters find the variance for the number who favor the measure
a. 1.9
b. 13
c. 4.6
d. 3.6
Here is my answer:
Given:
- 22% of voters favor a given ballot = 0.22
- Groups of 21 voters
So the variance is: 21*0.22 = 4.6
We choose B
