Answer 1

Explanation:

`\underline{ \underline{ \text{Given \: data}}} :`

• 10 , 2 , 8 , 9 , 5 , 2 , 6

`\underline{ \underline{ \text{Here :}}}`

• N ( total number of items ) = 7
• 
  `\tt \sum \: x \: = 10 + 2 + 8 + 9 + 5 + 2 + 6 = 42`

`\underline{ \underline{ \text{To \: find}}} :`

• Mean of the given data

`\underline{ \underline{ \text{Solution}}} :`

`\boxed{ \underline{ \tt{Mean = ( \sum \: x)/(n) }}}`

`\tt{ (42)/(7)}`

⟶
`\tt{6}`

`\pink{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \: 6}}}}}}`
