Q:
# If you are a human resources manager and you randomly selected 5 job candidates to interview out of hundreds of equally-qualified candidates that applied for a job without replacement, what would be the standard error of the mean if the standard deviation is 1?

Accepted Solution

A:

Answer:Standard error of mean = 0.4472 β 0.45Step-by-step explanation:Data provided in the question:Number of randomly selected candidates, n = 5Standard deviation of the data, Ο = 1Now,Standard error of mean is calculated using the formula asβ Standard error of mean = [tex]\frac{\textup{Standard deviation}}{\sqrt{n}}[/tex]
on substituting the respective values, we get
β Standard error of mean = [tex]\frac{\textup{1}}{\sqrt{5}}[/tex]
orβ Standard error of mean = [tex]\frac{\textup{1}}{\sqrt{5}}[/tex]
orβ Standard error of mean = [tex]\frac{\textup{1}}{2.236}[/tex]
orβ Standard error of mean = 0.4472 β 0.45
