You want to find the linear relation between the number of X-ray machines purchased at one time and the cost per machine. The following data has been obtained on the same:
X: Number of machines purchased | 1 | 3 | 6 | 10 | 15 |
Y: Cost per widget (in thousand rupees) | 89 | 85 | 79 | 73 | 64 |
Suppose the R² between X and Y is 0.87. Which of the following conclusions can you draw from this?
