If a protocol requires 75% accuracy, what data indicates this level of performance?

To determine if a protocol requires 75% accuracy, you need to calculate what represents 75% of the total responses in each case.

75% can be expressed as a decimal, which is 0.75. To find out how many correct responses are needed for a particular total number of attempts, you multiply the total number of attempts by 0.75.

For option B, with a total of 20 responses, you calculate:

0.75 x 20 = 15.

This means that for 75% accuracy, one would need to achieve 15 correct responses out of 20 attempts, and since the correct responses given are 15, this meets the requirement of 75%.

In contrast, if we look at the other options:

• For 10/15, 75% of 15 is 11.25, meaning at least 12 correct responses are needed.

• For 12/16, 75% of 16 is 12, so this option meets the criteria but not as well as the chosen answer under the question requirements.

• For 18/25, 75% of 25 is 18.75, indicating at least 19 correct responses are needed.
