Question
Hello,
value: 0.00 points The U.S. Dairy Industry wants to estimate the mean yearly milk consumption. A sample of 19 people reveals the mean yearly consumption to be 70 gallons with a standard deviation of 14 gallons. Assume that the population distribution is normal. (Use tDistribution Table.) a-1. What is the value of the population mean? 0 70 14 O Unknown a-2. What is the best estimate of this value? Estimate population mean C. For a 98% confidence interval, what is the value of t? (Round your answer to 3 decimal places.) Value oft d. Develop the 98% confidence interval for the population mean. (Round your answers to 3 decimal places.) nterval tor the population mean s and Confidence interval for the population mean is e. Would it be reasonable to conclude that the population mean is 58 gallons? O Yes O No O It is not possible to tell.Explanation / Answer
a-1)
unknown
a-2)
estimate population mean =70
c)degree of fredom =n-1=18
for 18 df and 98% CI
value of t =2.552
d)
std error =std deviaiton/(n)1/2 =3.212
confidence interval =sample mean -/+ t*std error =61.803 and 78.197
e)
No ; as it is outside of interval limits
