Question 1058595: The owner of Britten’s Egg Farm wants to estimate the mean number of eggs produced per chicken. A sample of 19 chickens shows they produced an average of 18 eggs per month with a standard deviation of 4 eggs per month. (Use t Distribution Table.)
a. What is the value of the population mean?
a.) 4
b.) It is unknown.
c.) 18
b. What is the best estimate of this value?
Best estimate:
c.
For a 98% confidence interval, what is the value of t? (Round your answer to 3 decimal places.)
Value of t:
d.
Develop the 98% confidence interval for the population mean. (Round your answers to 2 decimal places.)
Confidence interval from to .
e-1. Would it be reasonable to conclude that the population mean is 19 eggs?
a.) No
b.) Yes
e-2. What about 24 eggs?
a.) No
b.) Yes
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! a. The answer is b,
The best estimate is the sample mean of 18 eggs/mo.
98% CI interval width is t(df=18,0.99)s/sqrt(n); t=2.552.
That is 2.552*4/sqrt(19)=2.342
(15.66, 20.34)
Yes, it would be reasonable, because 19 is in the interval.
No, because 24 is not in the interval.
