The standard deviation of a normally distributed population is 24.0. A sample of size 4 is randomly selected. The standard error
1 answer:
The standard error of the mean is 12.
The standard error of the mean points to the standard deviation of the distribution of a sample mean obtained from a population.
The standard error S.E of the mean can be calculated by using the formula:
where;
- standard deviation
= 24
- sample size n = 4
S.E = 12

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
According to the image, the line goes through the following points:
So, the slope is:
Thus, the equation is of the form:
We substitute a point and find "b":
Finally, the equation is:
