Question

There are 34 questions on a test. John answers 22 of them correctly. What is John's percentage error?

Answer 1

35.29%

Step-by-step explanation:

no. of questions in test = 34

no. of questions answered correctly = 22

therefore, no. of questions answered incorrectly = 34 - 22

= 12

error percentage = 12/34 * 100

= 35.29%

Answer 2

Answer: John's percentage error is 35.3 %.

Step-by-step explanation:

To calculate the percentage error, we use the equation:

`\%\text{ error}=\frac{|\text{Experimental value - Accepted value}|}{\text{Accepted value}}* 100`

We are given:

Number of questions answered by John = 22

Total number of questions = 34

Putting values in above equation, we get:

`\%\text{ error}=(|22-34|)/(34)* 100\\\\\%\text{ error}=35.3\%`

Hence, John's percentage error is 35.3 %.
