Question 1044077: Construct the indicated confidence interval for the population mean muμ using a t-distribution.
cequals=0.9999, x overbarxequals=106106, sequals=1010, nequals=1919
The confidence interval is left parenthesis nothing comma nothing right parenthesis .(,).
(Round to the nearest tenth as needed.)
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! t distribution is essentially a z=distribution but the t-value (0.99995, df=1919)=3.90
SE=s/sqrt (n)=1010/sqrt(1919)=23.056
t*SE is one sided interval, and that is 3.90*23.056=89.9
(106016.1 , 106195.9)
