Question

find the standard deviation of the sampling distribution of sample means using the given information. Round to one decimal place if necessary. u=65 o=12 n=16

Answer 1

Solution :

Given that ,

mean = $\mu$ = 65

standard deviation = $\sigma$ =12

n = 16

$\mu$$\bar x$ = 65

standard deviation of the sampling distribution of sample means

$\sigma$$\bar x$ = $\sigma$ / $\sqrt$ n = 12/ $\sqrt$ 16 = 3

answer=3
