Answer:
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
Generally, ordered pairs represent a point on the coordinate plane. The first number in the ordered pair would be the x-coordinate and the second number in the ordered pair would be the y-coordinate.
