    Interpretation

    A friend who is taking AP Statistics at another school tells you that they did a problem in class whose answer was a 95% confidence interval for a population proportion of .35 + or - .04 (.35 plus or minus .04). He says that the class agreed on the following interpretation of this interval: "There is a 95% chance that the true value of p is in this interval." Describe how you would explain to your friend that this interpretation is wrong.

    All help is appreciated, thanks.

    I've been trying to solve this problem and would the problem lay within the .04? Is there some kind of rule that states with a certain confidence level a certain range must be met? Sorry for the bump, just trying to encourage responses.

    You shouldn't bump, in general it won't help have your question answered any quicker.

    The correct interpretation is:

    The true value of p will fall in 95 out of 100 sampled confidence intervals.

    Thanks for the help, it just seems that this board has less viewers than the Calculus one.

    In my experience here at MHF, the Mods, Helpers and Experts seem to cover all sub-forums quite evenly.

    Or is the Calculus board you speak of in another forum altogether?
