The standard deviation for a set of data is 5.5. the mean is 265. what is the margin of error?

The margin of error for the give set of data = 10.78

Step-by-step explanation:

Standard deviation = 5.5

Mean = 265

To calculate the margin of error for the given set of data : Simply multiply the given standard deviation with the associated z score

Now, the confidence level is not given. So, assume the confidence level to be 95%

Z-score for 95% confidence level = 1.96

Therefore, Margin of error = Z-score for 95% confidence level × Standard deviation

⇒ Margin of error = 1.96 × 5.5

⇒ Margin of error = 10.78

Hence, the margin of error for the give set of data = 10.78
