Question 1171724: Suppose you have selected a random sample of n = 11 measurements from a normal distribution. Compare the standard normal z values with the corresponding t values if you were forming the following confidence intervals.
(a) \ 98% confidence interval
z =
t =
(b) \ 95% confidence interval
z =
t =
(c) \ 80% confidence interval
z =
t =
You can put this solution on YOUR website! 98% is 2.326 for normal
95% is 1.96 for normal
80% is 1.28 for normal
for t df=10, 2.764 (98)
2.228 (95)
1.372 (80)
