Answer:

The answer is "16%".

Step-by-step explanation:

Its empirical rule suggests which 68% of the very first standard deviation, 95% of the very first 2 standard deviations or 99.7% of the very first three standard deviations of the variance average fall.

[tex]z =647 \\\\z=\frac{(647-547)}{100}= \frac{100}{100}=1[/tex]

The empirical rule indicates the first standard deviation around 68 percent.

So,

[tex]=\frac{(100-68)}{2} \\\\=\frac{32}{2} \\\\= 16 \% \ drop \ 647 \ and \ above[/tex]
