SOLUTION: I'm stuck with this inequality. a < x bar - mu < b supposedly this solves to: x bar - a < mu < x bar + b The sad thing is I'm 79 and writing a stat book. Thanks; joe b.

supposedly this solves to: x bar - a < mu < x bar + b

You can put this solution on YOUR website!
a+%3C+x-+mu+%3C+b
Multiply all sides by -1,
-a+%3E+-x%2B+mu+%3E+-b
Add x to all sides,
x-a%3Emu%3Ex-b
x-b%3Cmu%3Cx-a
Not the same as what you wrote but it is correct.
