Review Arithmetic averages before starting →Ideas to recall
- The arithmetic mean equals the sum of the values divided by the number of values.
- Multiplying the mean by the number of values recovers the total.
- A missing value can be found by subtracting known values from the required total.
- The mean is not necessarily one of the values in the data set.
Use these ideas to reason through each question; answer-specific explanations appear only after you check a response.
