To calculate the range of the data shown in the histogram, we first need to find the minimum and maximum number of servings of vegetables eaten. From the data provided in the histogram:
Minimum number of servings = 0
Maximum number of servings = 10
Range = Maximum value - Minimum value
Range = 10 - 0
Range = 10
Therefore, the range of the data shown in the histogram is 10 servings of vegetables.
