Answer:
The margin of error for a 99% confidence interval for the population mean is 1.8025.
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 problem:
So
The margin of error for a 99% confidence interval for the population mean is 1.8025.
Answer:
2y + 4z = x
Step-by-step explanation:
Given
Required
Write an equation that which is true for the above parameters
<em>This question will be answered using trial by error method and the solution is not limited to one equation.</em>
<em></em>
One equation that matches the values above is:.
To check:
Substitute the values of x, y and z in the above equation.
Hence,
Because both sides of the equation are one and the same (-4), is true for the above values of x, y and z.
