The scatter graph indicates that lighter laptops generally cost more (B), heavier laptops tend to cost less (C), and there's a trend of laptops getting lighter over the observed data (E).
The correct conclusions based on the scatter graph are as follows:
B) Lighter laptops cost more, as there seems to be a negative correlation indicating that lighter laptops generally have higher prices.
C) Heavier laptops cost less, given the negative correlation, suggesting that heavier laptops tend to be associated with lower prices.
E) Laptops are getting lighter, supported by the overall trend in the scatter graph showing a decline in laptop weights over the observed data points.
These conclusions align with the visual representation of the data, demonstrating the relationships between laptop weight and cost on the scatter graph.
