THE ANSWER IS 5.6! Just ttook the test
Step-by-step explanation:
If the standard deviation of a population is 2.8. The margin of error is 5.6.
Margin of error formula is:
Margin of error=z×α/√n
Since we were only given the standard deviation(α) the margin of error will be:
Margin of error=2.8×2.8
Margin of error =5.6
Therefore if the standard deviation of a population is 2.8. The margin of error is 5.6.
