Hi, can you help me answer this question please, thank you

Using the 68-95-99.7% rule;
[tex]\begin{gathered} z=\frac{x-\mu}{\sigma} \\ z=\frac{11-35}{8} \\ z=-\frac{24}{3} \\ z=-3 \\ z=\frac{27-35}{8} \\ z=-\frac{8}{8} \\ z=-1 \\ \end{gathered}[/tex]Then, we have;
Thus;
[tex]P(-3Hence, the approximate percentage is;[tex]15.73[/tex]
