    A poll was conducted that asked 1015 people how many books they had read inthe past year. The results indicated that mean is 11.5 books and standard deviation is 4.6 books.Construct a 96% confidence interval for the mean number of books people read.Please help me with this and show as much work as possible out to thousandths place.

    This is ridiculous. You are not asking for guidance, but rather a specific solution set.God help us all if you pass ASQ BB.

    HeeBee, my man – you took the bait, hook, line, and sinker.If this was a real post, the only appropriate response is – Do your own homework.I suspect, though, that it was a set-up by Freddy looking to entice the rabble.

    MBBWIXYZ,
    hitting the Dewer’s on the rocks a bit early, no?
    Your recent posts don’t “sound” like the old MBBWIXYZ…they are a bit loosy-goosey, hippy dippy…remember to get a cab tonight.
    ;-)
    (that was sarcasm, freddy)

    Dewars?  I’d wash your mouth out with soap if I knew who you were,  which would still taste better than Dewars.  It’s Glenfiddich, if you please!

    HAH! nothing wrong with a good blended, mbb.
    Glenfidditch is a good single, but there is room for diversity in “Le Cafe Six Sigma and Jazz bar”.see Freddy? we can S&S and still be civil, because in the end, none of it matters, if the mantra of bottom line results isn’t drilled into our up and coming practitioners heads.

    Yes, hb, and much of comedy uses sarcasm effectively. That was never my argument. We were talking about motivating people to accomplish their best.

    Most text books have what you need, filed under “Confidence Intervals”, subcategory “of the mean”.
    Your posting does violate a rule:  You cannot get more lemon juice from a lemon that what is inside the lemon.  (Otherwise known as significant digits.)  Your input data is to the nearest tenth, yet you are asking for an output that is100 times more accurate.  That should not be – neither in my shop nor in yours.  Review significant digit rules first.

    Nah, with this crew no enticing is needed. It’s a natural feeding frenzy.
