![**Understanding Normal Distribution of HD Television Prices**
The graph provided represents a normal distribution for the prices paid for a specific model of HD television. It indicates that the mean price is $2000, with a standard deviation of $70.
**Graph Explanation:**
The bell-shaped curve is symmetrical, centered at the mean price of $2000. The x-axis represents the distribution of prices, ranging from $1790 to $2210, with key points at $1860, $1930, $2000, $2070, and $2140, reflecting increments of the standard deviation.
