You can put this solution on YOUR website! You take a random sample from some population and form a 96% confidence interval for the population mean, μ Which quantity is guaranteed to be in the interval you form?
a) μ
b) 0
c) 0.96
d) sample mean x-bar
----
Ans: x-bar
Note: x-bar is ALWAYS the center of the confidence interval.
CI:: (x-bar-ME,x-bar+ME)
Find the average or middle:: (x-bar-ME + x-bar+ME)/2 = 2(x-bar)/2 = x-bar
