To make n the subject of formula.
Cross-multiplying, we have;
Rearranging the equation, we have;
C ⠀ ⠀ ⠀ ⠀ ⠀
The points between 0 and 1 increase in increments of 1/6th
Standard error of the mean is computed by:
Standard error = SD/ sqrt N
Where:
N is the sample size
SD is the standard deviation
To get the standard deviation, you need to get the sqrt of
the variance = sqrt 9 = 3
So plugging in our data:
Standard error = 3 / sqrt (16)
= 0.75
