QuestionGiven the following data points:\text{Given the following data points:} \begin{align*} &\text{Shoe size (pointure de Soulier): 6, Foot length (longueur du pied): 20, Height (hauteur): 146.5} \\ &\text{Shoe size (pointure de Soulier): 6.5, Foot length (longueur du pied): 24, Height (hauteur): 162} \\ &\text{Shoe size (pointure de Soulier): 7, Foot length (longueur du pied): 22.5, Height (hauteur): 163} \\ &\text{Shoe size (pointure de Soulier): 7, Foot length (longueur du pied): 23, Height (hauteur): 166} \\ &\text{Shoe size (pointure de Soulier): 7, Foot length (longueur du pied): 18, Height (hauteur): 169} \\ &\text{Shoe size (pointure de Soulier): 7, Foot length (longueur du pied): \text{unknown}, Height (hauteur): \text{unknown}} \end{align*}
Using a linear model, predict the height for the last data point with a shoe size of 7.\text{Using a linear model, predict the height for the last data point with a shoe size of 7.}
Determine whether interpolation or extrapolation is used in this prediction.\text{Determine whether interpolation or extrapolation is used in this prediction.}

Studdy Solution
Determine if the prediction involves interpolation or extrapolation. Since the shoe size of 7 is within the range of the given data points, the prediction involves interpolation.
The predicted height for a shoe size of 7 is:
166\boxed{166}
The prediction involves interpolation.
