Reconsider the previous three exercises and the Legos data file. The equation of the least squares line turns out to be price = 4.86 + 0.105 × pieces, and the value of r² = 0.949. Identify which of the following interpretations are correct, which are incorrect, and which are correct but incomplete or poorly worded.
a. 10.50% of the variability in prices is explained by the least squares line with number of pieces.
b. 94.90% of the variability in prices is explained by the least squares line with number of pieces.
c. 94.90% of the prices fall on the least squares line based on number of pieces.
d. The least squares line correctly predicts the price for 94.90% of the Lego products.
