    Step-by-step explanation:

    Required

    The average

    The data whose average is to be calculated are not given.

    However, the formula to calculate the average is:

    \bar x = \frac{\sum x}{n}

    Assume the data is:

    1287\ 1215\ 1221\ 1229

    This means that the number of schools is 4

    So:

    \bar x = \frac{1287+ 1215+ 1221+ 1229}{4}

    \bar x = \frac{4952}{4}

    \bar x = 1238

    The average of the assumed data is 1238
