The Plus four method is appropriate when the sample size is small, in this case only 9 students responded to the survey. The Plus four method adds 2 to the number of successes and 2 to the number of failures to account for the uncertainty in the data, resulting in a sample of 11 with 7 successes and 4 failures. This allows for a more accurate estimation of the confidence interval.
