Question 872919: A random sample of 100 rates of return on real estate investments were
computed and recorded. Assuming that the standard deviation of all rates of
return on real estate investments is 2.5% and sample mean is 12.
(a) Estimate the mean rate of return on all real estate investments with 95%
confidence.
(b) Discuss the assumptions of binomial distribution. Answer by oscargut(2103) (Show Source):
You can put this solution on YOUR website! a)
CI is:
Lower limit 12 - 1.96(2.5)/10 = 11.51
Upper limit: 12 + 1.96(2.5)/10 = 12.49
Answer: (11.51,12.49)
