8) In the following statement, which is the margin of error?
200 Americans were asked which subject they think about most. 65% +/- 10% said they think of Statistics the most.
A) 200
B) None of the Above
C) 55% to 75%
D) 65%
E) +/- 10%
Try E.
E +/-10%
In the given statement, "65% +/- 10%" is the margin of error.
To understand how to identify the margin of error in this statement, it is important to first understand what margin of error represents.
Margin of error is a statistical term that refers to the amount of uncertainty or error associated with survey data or poll results. It measures the range within which the true population parameter is likely to fall. In this case, it indicates the range of values within which the true percentage of Americans who think about Statistics the most is likely to lie.
In the given statement, the margin of error is expressed as "+/- 10%" after the reported percentage of 65%. The "+/-" symbol indicates that the margin of error should be added to and subtracted from the reported percentage to determine the range.
Therefore, in this case, the margin of error is 10%, which means the actual percentage of Americans who think about Statistics the most could range from 55% to 75%.
