Answer: See explanation 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 Reply

Step-by-step explanation:RequiredThe 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 4So:[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
