Answer
Answer:
extrapolation, because a key that is 12 keys from middle C is outside the data set
Brief Explanations:
- First, identify the range of the given data set: the number of keys above middle C in the table ranges from 0 to 8.
- A key 12 keys from middle C falls outside this 0-8 range.
- Interpolation refers to predicting values within the existing data range, while extrapolation refers to predicting values outside the existing data range. Thus, this is extrapolation.
