Answer 1

`\begin{gathered} \text{ mean=26} \\ \text{ median=27} \\ \text{ mode=28} \\ \text{ range=9} \end{gathered}`

Explanation:

The mean of a sample of data is the addition of all the numbers by the number of elements:

`\begin{gathered} \text{ mean=}(21+23+26+28+28+30)/(6) \\ \text{ mean=26} \end{gathered}`

The median is the middle number from the list of numbers organized from least to highest.

`\text{ median=27}`

The mode is the values that occur more frequently:

`\text{ mode= 28}`

The range is the difference between the highest value and the lowest value:

`\begin{gathered} \text{ Range=30-21} \\ \text{ Range=9} \end{gathered}`
