Question
value: 0.00 points The U.S. Dairy Industry wants to estimate the mean yearly milk consumption. A sample of 25 people reveals the mean yearly consumption to be 82 gallons with a standard deviation of 24 gallons. Assume that the population distribution is nomal. (Use t Distribution Table) a-1. What is the value of the population mean? O Unknown O 24 O 82 a-2. What is the best estimate of this value? Estimate population mean C. For a 90% confidence interval, what is the value of t? (Round your answer to 3 decimal places.) Value oft d. Develop the 90% confidence interval for the population mean. (Round your answers to 3 decimal places.) Confidence interval for the population mean is e. Would it be reasonable to conclude that the population mean is 75 gallons? O No O Yes OIt is not possible to tell.Explanation / Answer
Solution:- Given that n = 25 , X = 82 , sd = 24
df = n-1 = 25-1 = 24
t = 1.711
a-1. option A. Unknown
a-2. Estimate population mean 82
c. value t = 1.711
d. confidence interval for the population mean is 73.618 and 90.382
=> X +/- t*s/sqrt(n)
= 82 +/- 1.711*24/sqrt(24)
= 73.618 , 90.382
e. option B. Yes
