The standard deviation for a set of data is 6.5. The mean is 255. What is the Margin of Error?
1 answer:
Answer: The margin of error is 12.74.
Step-by-step explanation:
Since we have given that
Standard deviation = 6.5
Mean = 255
Let 95% level of significance,
So, z value = 1.96
We need to find the "Margin of error":
So, it becomes :
Margin of error = Standard deviation × z-value
Margin of error =
Hence, the margin of error is 12.74.

Step-by-step explanation:
If the point Q that is located two over three the distance from point P to point R, then PQ:QR=2:3.
Use formula to find the coordinates of the point Q:
In your case, P(-2,7) and R(1,0), then
