Question

In a basket of 11 oranges, 2 rotten oranges are mixed. An orange is drawn with replacement.This experiment is repeated 20 times. The probability distribution for the data collected empirically is given as follows.

Answer 1

The standard deviation is given by:

`S=\sqrt[](\Sigma`

so:

`\begin{gathered} \mu=1\cdot((4)/(10))+2\cdot((2)/(10))+3\cdot((4)/(10)) \\ \mu=2 \end{gathered}`
`\begin{gathered} S=(5)/(10) \\ S=0.5 \end{gathered}`
