Question

(find percent error) a political analyst predicts Mr. Smith will only get 122 votes for mayor. if Mr. Smith only gets 57 votes, what is the political analyst's percent error? round your answer to the nearest tenth of a percent.

Answer 1

The difference between the prediction & the reality is 122-57 =65 votes.

Then over 122, the error was 65 votes &

the error ratio is 65/122 = 0.5327 ==>53.27% Or 53.3% (rounded)

Answer 2

Answer: 114%

Step-by-step explanation:

The formula to calculate percent error is :-

$\text{Percent error}=\frac{|\text{predicted-actual}|}{\text{actual}}\times100$

Given: The predicted value =122

The actual value =57

Substitute the values in the above formula ,we get

$\text{Percent error}=\frac{|122-57|}{57}\times100\\\\=\frac{65}{57}\times100\\\\=1.14035087719\times100\\\\=114.035087719\%\approx114.0\%$
