Independent Variable

Answer 2

first question:

C) 4440 to 5400 voters

if 12,000 voters are participating in the election, 41% of them = 4,920 people.

Now we must add and subtract 4% of the total voters to 4,920 people. 4% of the total voters = 480

• 4,920 - 480 = 4,440 votes
• 4,920 + 480 = 5,400 votes

second question:

C) Sampling

Since the federal government has a lot of employees, a census would be really expensive and time consuming. on the other hand experimental or observational studies do not apply in this situation.

The only possible solution would be sampling study due to the high costs of a census. The sampling study requires that a certain amount of samples (teenage employees) are surveyed to determine their average hourly wage.
