For the population, u= 15 and o=4. If the researcher randomly samples 36 participants, what is the average distance in the distribution of sample means?
Solution :
Given that ,
mean = = 15
standard deviation = = 4
n = 36
sample distribution of sample mean is ,
=
= 15
sampling distribution of standard deviation
= / n = 4 / 36=0.67
= 0.67
