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?

Homework Answers

Answer #1

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
