Based on the information provided, here’s how the sale of the keepsake baseball for $9.49 will affect the mean and the range of the prices of the remaining Jackie Robinson items in the store.
1. **Mean Price Impact**:
- After the sale of the keepsake baseball for $9.49, the mean price of the Jackie Robinson merchandise will **decrease**.
- This is because the sold item (priced at $9.49) is below the average price of the remaining items. A lower priced item being taken out lowers the overall average.
2. **Range of Item Prices Impact**:
- The range of item prices after the sale will **stay the same**.
- The range is defined as the difference between the highest and lowest prices. Since the keepsake baseball is sold and is not the highest priced item, the highest price remains unchanged, and the lowest price will be the next lowest item if the baseball was the lowest.
So, putting it together:
**Based on the histogram, the mean price of the Jackie Robinson merchandise after the keepsake baseball is sold will** **decrease** **because** **the sold item is lower than the average price of the remaining items in the store.
