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
