<PRE><B>Question 980616</B>
 Use the given degree of confidence and sample data to construct a confidence interval for the population mean &amp;#956;. Assume
that the population has a normal distribution.
n = 10, x-bar = 8.1, s = 4.8, 95% confidence
-----
Confidence Interval:: x-bar - ME &lt; u &lt; x-bar + ME
------
ME = 1.96*4.8/sqrt(10) = 2.975
-------
95%CI: 8.1-2.98 &lt; u &lt; 8.1+2.98
-------
Ans: 5.12 &lt; u &lt; 11.08
----------
