Questions & Answers

Q: Can a salesperson in the scenario sell more than 10 cars?

No, it is not possible for a salesperson to sell more than 10 cars. This is because the range of car sales is only four, and the median value is six, indicating that the maximum number of cars sold will be 10.

Q: How is the range calculated?

The range is calculated by subtracting the minimum number of cars sold from the maximum number. It represents the difference between the highest and lowest car sales.

Q: Why is it not possible for the minimum value to be seven?

It is not possible for the minimum value to be seven because the given median value is six. In a dataset with an odd number of data points, the median represents the middle value, and there will always be values lower than the median. Thus, the minimum value must be equal to or lower than six.

Q: What does the median value represent?

The median value represents the middle number in an ordered list of numbers. In the context of the car sales scenario, it indicates the car sales number that divides the dataset into two equal halves.
