Answer:
The margin of error needed to create a 99% confidence interval estimate of the mean of the population is of 0.3547
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
In this question:
So
The margin of error needed to create a 99% confidence interval estimate of the mean of the population is of 0.3547
The segment was only rotated, not changed. It would be the same length as the original.
To find the length, use the distance formula.
(5, 8) would be point 1.
(-6,8) would be point 2.
Plug them into the formula.
Simplify.
Square root this answer.
Negative distances aren't possible, so your answer is 11.
Hope this helped!
