Stat help. K2=95% confidence

  1. Jan 19, 2013 #1
    To capture the actual Rent amount 95% of the time, predictions from the fitted equation should include a margin of error of about plus or minus ______ (round to the nearest ten dollars).
    $128
    $114 (answer)
    $57
    $228
    Here's a pic of the table. How did they get the answer? http://picturetrail.com/sfx/album/view/24285022
    I know k2= 95%. I know you do 2 * (standard error) but I don't see that on the table.

    Is this an inference for regression test that you're doing?
