Solution by Steps
step 2
The median is the middle number in a sorted list of numbers. With 7 models, the 4th appearance number is the median, which is 5
step 3
The range is the difference between the highest and lowest values. A range of 5 means that the difference between the most and least number of appearances is 5
step 4
If the fewest appearances were 1, then the highest number of appearances could be 1 + 5 = 6 to maintain the range of 5
step 5
Since the median is 5, there must be three values less than or equal to 5 and three values greater than or equal to 5. Having 1 as the fewest number does not contradict this requirement
