To find the median amount of sales from the given data, you first need to list the total sales amounts in order, which they already are:
- $4,000
- $5,000
- $6,000
- $7,000
- $8,000
- $9,000
Since there are six values (an even number), the median will be the average of the two middle numbers. The two middle numbers are the 3rd and 4th values:
- 3rd value: $6,000
- 4th value: $7,000
Now, calculate the average of these two values:
\[ \text{Median} = \frac{6,000 + 7,000}{2} = \frac{13,000}{2} = 6,500 \]
Thus, the median amount of sales each day is $6,500.
