Answer 1

To determine the valid inference based on the scatterplot data, you need to analyze the direction of the correlation between gas prices and hybrid car sales.

• Response A suggests that as gas prices increase, hybrid car sales decrease. This indicates a negative correlation.
• Response B states that there is no correlation, implying that changes in gas prices have no effect on hybrid car sales.
• Response C indicates that as gas prices increase, hybrid car sales also increase, which suggests a positive correlation.

If the scatterplot shows points that trend downward (suggesting that as gas prices go up, hybrid car sales go down), then Response A would be valid. If the points show no discernible trend, Response B would be the correct inference. If the points trend upward (indicating that higher gas prices lead to more hybrid car sales), then Response C would be valid.

Without seeing the scatterplot, I cannot definitively choose the correct response. Please examine the trends in the scatterplot to make the appropriate choice.
