After conducting a survey of all her classmates, midge discovers that the amount of money everyone spends buying books each month has a mean of $30. what does the mean say about the amount her classmates spend on books? half of her classmates spend exactly $30 per month buying books. half of her classmates spend more than $30 per month buying books. the majority of her classmates spend $30 per month buying books. if the amount spent on books per month by all her the classmates is leveled, that amount would be $30.

The mean is the average of the numbers: a calculated "central" value of a set of numbers.

Therefore: If the amount spent on books per month by all her classmates is leveled that amount would be $30

To calculate it: add up all the numbers, then divide by how many numbers there are
