Question 1059876: Construct the indicated confidence interval for the population mean
muμ
using the​ t-distribution
cequals=0.90

x overbarxequals=14.1
sequals=2.0
nequals=7
The
9090​%
confidence interval using a​ t-distribution is left parenthesis nothing comma nothing right parenthesis .(m,m).

Construct the indicated confidence interval for the population mean
muμ
using the​ t-distribution
c = 0.90
----
-invT(0.05,6) = 1.9432
x-bar = 14.1
s = 2.0
n = 7
------
sample mean:: 14.1
ME = 1.9432*2/sqrt(7) = 1.467
The 90​% CI:: 14.1-1.467 < u < 14.1+1.467
---
Ans: (12.633 , 15.569)
