Question

janna is making a prediction of the frequency of a key that is 12 keys from middle c. which best describes her prediction? interpolation, because a key that is 12 keys from middle c is within the data set interpolation, because a key that is 12 keys from middle c is outside the data set extrapolation, because a key that is 12 keys from middle c is within the data set extrapolation, because a key that is 12 keys from middle c is outside the data set

Explanation:

Interpolation is used for values within the data - set range, while extrapolation is for values outside. The data - set has keys \(0,1,2,4,8\) and \(12\) is not in this set.

Answer:

extrapolation, because a key that is 12 keys from middle C is outside the data set
