    Question

    The table below shows the association between sports and general well-being. In the table, the standardized residuals are shown in parentheses. Which interpretation of the standardized residue -1.3 is correct?

    ——— ———————- ————— ———— Sports General well-being Not so good Fairly Very good Never 20 (11.2) 14 (-1.3) 3 (-4.1) Sometimes 35 (1.4) 395 (14.7) 75 (-15.5) Often 30 (-5.8) 310 (-13.8) 515 (16.1) ——— ———————- ————— ————


    1. TRUE: The observed number of 14 in this cell is 1.3 standard error less than the expected number.
    2. FALSE: The observed number of 14 in this cell minus 1.3 standard error gives the expected value.
    3. FALSE: Since the standardized residual is negative, there is no dependence.

    1. The observed number of 14 in this cell is 1.3 standard error lower than the expected number…: Correct
    2. The observed number of 14 in this cell minus 1.3 standard error gives the expected value…: Incorrect
    3. Because the standardized residual is negative, there is no dependence: Incorrect
