The standard deviation for a set of data is 9.5 the mean is 205 what is the margin of error

Answer: 19

Step-by-step explanation: i just took the test; )

The margin of error = 19

Step-by-step explanation:

The formula to calculate the margin of error is

ME = Critical value * Standard deviation

Since, the critical value isn't given and let us assume that the confidence interval is 95%, then the critical value is 1.96

Substituting the values in the formula, we get,

ME = 1.96 * 9.5

ME = 18.62

ME = 19

Thus, the margin of error is 19.
