Refer to Exercise 4.77. Describe the sampling distribution for the sample sum Is it unlikely (improbable) that would be more than 70 units away from 960? Explain.
REFERENCE:
4.77 : A random sample of 16 measurements is drawn from a population with a mean of 60 and a standard deviation of 5. Describe the sampling distribution of the sample mean. Within what interval would you expect to lie approximately 95% of the time?
