    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:

    [tex]\bar x = \frac{\sum x}{n}[/tex]

    Assume the data is:

    [tex]1287\ 1215\ 1221\ 1229[/tex]

    This means that the number of schools is 4

    So:

    [tex]\bar x = \frac{1287+ 1215+ 1221+ 1229}{4}[/tex]

    [tex]\bar x = \frac{4952}{4}[/tex]

    [tex]\bar x = 1238[/tex]

    The average of the assumed data is 1238
