What is the equation.

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
