What is the average (with 0 decimal places) across all schools for the total score? Group of answer choices 1287 1215 1221 1229
Irina18 [472]

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:

\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

<em>The average of the assumed data is 1238</em>
