AJ is trying tо predict hоw lоng it will tаke him to reаd аny given book based on the number of pages. He took a random sample of 60 books and did a regression analysis on time it takes to read the book (in minutes) on length of the book (in pages). The computer output below is a result of his analysis: The table shows that the number of pages is a strong predictor of the outcome. For each extra page, the outcome increases by about 2.15. The starting value (constant) is less reliable, but overall the model explains about 96.7% of the variation, which means it fits the data very well. Interpret the value of the coefficient of determination () in the context of this problem.
