15.00 points Exercise 9-12 (LO9-2) The U S Dairy Industry wants to estmate the mean yearly milk consumption A sample ot 11 people reveal s the mean yearly consumption to be 54 gallons with a standard deviation of 15 gallions. Assume that the population distribution is normal. (Use tDistributon Table) a 1, what is the value of the population mean? 54 0 15 a-2. What is the best estimate of this value? Estimate popuiation mear nd your answer to 3 decimal places.) c. For a 98% confidence interval, what is the value of n (Rou d. Develop the 98% confidence interval for the population mean (Round your answers to places.) Confidence interval for the population meanis Would it be reasonable to conclude that the population mean is 65 galons? Sign in e. Yes O No is not possible to tell Exercise 9-12 (L09-2) Worksheet

Explanation / Answer

Solution:-

a-1. option C. unknown

a-2. Estimate population mean 54

c. value of t 2.764
=> t(0.01,10) = 2.764

d. confidence interval for the population mean is 41.499 and 66.501
=> X +/- t * s/sqrt(n)
= 54 +/- 2.764 * 15/sqrt(11)
= (41.499 , 66.501)

e. option A. Yes.
