Answer:
The standard deviation for the sampling distribution of the sample mean is 6000.
Explanation:
Standard deviation of the population is given as 12000 and we know that the sample has 4 electricians and therefore the standard error is 12000/sqrt(4) = 6000
Therefore , The standard deviation for the sampling distribution of the sample mean is 6000.
Answer:
$6,000
Explanation:
The standard deviation of the sampling distribution of the mean is a measure of the difference between the observed values and the mean in a dataset. It is calculated using the formula:
σм= σ/[tex]\sqrt{n} \\[/tex]
σ= standard deviation
n= sample size
σм= $12,000/[tex]\sqrt{4}[/tex]
σм= $12,000/2
σм= $6,000
The standard deviation for the sampling distribution of the sample mean is $6,000.
