Question

Yield of soybeans per acre in quintal in mukund's field for 7 years was 10,7,5,3,9,6,9 find the mean of yield par acre ​

Answer 1

We know that

$\\ \small\sf{Mean = \dfrac{Sum~ Of~ Observation}{Number\ of\ Observation } }$

$\sf{Mean = \dfrac{10 + 7 + 5 + 3 + 9 + 6 + 9}{7 } }$

$\sf{Mean = \dfrac{49}{7 } }$

$\sf{Mean = 7 }$

Hence, the mean of yield par acre is 7.

Answer 2

$\huge \mathbb{ \red {★᭄ꦿ᭄S} \pink{ᴏ}\purple{ʟᴜ} \blue {ᴛ} \orange{ɪ} \green{ᴏɴ★᭄ꦿ᭄}}$

• ↪We know that.

$\begin{gathered} \\ \small\tt \red{Mean = \dfrac{Sum~ Of~ Observation}{Number\ of\ Observation } }\end{gathered}$

$\tt \pink{Mean = \dfrac{10 + 7 + 5 + 3 + 9 + 6 + 9}{7 } }$

$\tt \purple{Mean = \dfrac{49}{7 } }$

$\tt \orange{Mean = 7 }$

• ↪Hence, the mean of yield par acre is 7.
