Answer 1

Answer: See below

Explanation:

4)
`p(5.8 < x < 8.8)=0.7838` (By calculator)

5)
`p(x \leq 4.8)=0.0032` (By calculator)

6)
`P(x > 9.8 \text { or } x < 5.8)= P(x < 5.8)+P(x > 980)`

`\begin{array}{ll}\text { Now } \quad & P(x > 9.8)=0.0345 \\\text { and } \quad & P(x < 5.8)=0.0345\end{array}`

`p(x > 9: 8 \text { or } x < 5.8)=0.069`

7) No, there are no outliers in the data set
