Answer:
The sample mean is 3.48 and the margin of error is 0.44.
Step-by-step explanation:
We know that the confidence interval is written in the form "x − E to x + E", meaning x: sample mean or estimator, and E: margin of error.
To calculate the mean, we can calculate the average of both bounds of the confidence interval:
With one of the bounds, we can calculate the margin of error E
Answer:
yes she did
Step-by-step explanation:
First change the fraction to a decimal by multiplying both sides by 2. 49 times is 98. Therefore, you have to put it as 0.98. Now you put the 686 in place of the 0. The final answer is 696.98.
Well let's say x = -1000
That's what I would do
-48n + 408 Multiply length times width : 24(-2n + 17) distribute the 24.
