Question

Find the standard deviation of the sampling distribution of sample means using the given informationRound to one decimal place, if necessary mu=67 ando sigma=12.n=36

Answer 1

Solution :

Given that,

mean = = 67

standard deviation = = 12

n = 36

The sampling distribution of mean and standard deviation is ,

= 67 and

= / n = 12 / 36 = 2
