Answer:
Normal distribution.
Median is 5.5.
Range is 8.
Explanation:
The given distribution is a normal distribution because it's symmetrical.
The median is the value in the middle. There are 28 elements, so, the median is between the 14th and 15th element, that is:
![(5+6)/(2)=5.5](https://img.qammunity.org/2021/formulas/mathematics/high-school/tcm8ve4z9zge46i583t6iwi00nuafxqdwk.png)
So, the median is 5.5.
The range is the difference between the greatest value and the least, which is
![10-2=8](https://img.qammunity.org/2021/formulas/mathematics/high-school/npevfwmssdw9tx6jpx2j0im4bhbipezpnm.png)
Therefore, the range is 8.
