Question

The owner of Britten’s Egg Farm wants to estimate the mean number of eggs produced per chicken. A sample of 20 chickens shows they produced an average of 19 eggs per month with a standard deviation of 5 eggs per month. (Use z Distribution Table.)

For a 90% confidence interval, what is the value of t? (Round your answer to 3 decimal places.)

Develop the 90% confidence interval for the population mean. (Round your answers to 2 decimal places.)

Explanation / Answer

a)

mean = 19

b)

best estimate = 19

c)

value of t for 1-0.90= 0.10

alpha/2 = 0.05

df = 19

t=1.729

d)

I: 19 +/- 1.729* 5/ srqt(20)

I: 19 +/- 1.933

I: [ 17.067 . 20.933 ]

e)

No

f)

No

as you can see the interval of confidence dont have those values on it
