Find the standard deviation of the sampling distribution of sample means using the given information. Round to one decimal place, if necessary.
μ=69
and σ=12
; n=64
The formula for the standard deviation of the sampling distribution of sample means is:
Standard deviation of sample means = σ / √n
Plugging in the values given:
Standard deviation of sample means = 12 / √64
Standard deviation of sample means = 12 / 8
Standard deviation of sample means = 1.5
Therefore, the standard deviation of the sampling distribution of sample means is 1.5.
