Answer 1

The answer is 4.4% for K12

Answer 2

`\boxed{\boxed{\%\ error=4.4\%}}`

Explanation:

Daniel guessed that he would score 95 on his science test, but his actual score was 91.

We know that,

`\%\ error=\frac{|\text{Expected value - True value}|}{\text{True value}}* 100`

Here,

Expected value = 95

True value = 91

Putting the values,

`\%\ error=\frac{|\text{95 - 91}|}{\text{91}}* 100\\\\=\frac{|\text{4}|}{\text{91}}* 100\\\\=\frac{4}{\text{91}}* 100\\\\=4.39\approx 4.4\%`
