Calculate the mean, median, mode and range for the following Sales data: 1,700, 2,200, 2,400, 2,900, 1,800, 3,700, 1,200, 2,300, 600, 1,600, 2,000, 3,900, 1,100, 1,700, 2,900, 2,900, $2,900. Then, interpret the result.

You correctly re-arranged the sales data in ascending order:
$600,$1100, $1200,$1600, $1700,$1700, $1800,$2000, $2200,$2300, $2400,$2900, $2900,$2900, $2900,$3700, $3900. There are$n=17$ data points.
Let's re-sum the values:

Your sum of $37,100 was slightly off. The correct sum is$37,600.

The mean is the sum of all values divided by the number of values.

Rounding to two decimal places:
The mean is \boxed{\mathbf{\2211.76}}$.

The mean of $2211.76 indicates that the *average* sales value across all 17 data points is approximately$2211.76. It represents the central tendency of the sales data.

Since there are 17 data points (an odd number), the median is the $((n+1)/2)$-th value in the ordered list.

Counting to the 9th value in the ordered list:
$600, 1100, 1200, 1600, 1700, 1700, 1800, 2000, \mathbf{2200}, 2300, 2400, 2900, 2900, 2900, 2900, 3700, 3900$.
The median is \boxed{\mathbf{\2200}}$.

The mode is the value that appears most frequently in the dataset.
The value $2900 appears 4 times, which is more than any other value. The mode is$\boxed{\mathbf{$2900}}$.

The range is the difference between the maximum and minimum values in the dataset. $\text{Range} = \text{Maximum Value} - \text{Minimum Value} = \$3900 - \$600 = \$3300$ The range is \boxed{\mathbf{\3300}}$.
