A teacher believes that students with natural music abilities are more likely to be left-handed than typical students are. To test this, a random sample of 80 students in a performing arts school were selected. The results showed that 25 of these students were left-handed. Within the general population, it has been determined that 20% of students are left-handed. Can it be concluded that the percentage of students in the performing arts school who are left-handed is greater than 20%? Formulate and test the appropriate hypotheses at a 1% significance level, using both the critical value approach and the -value p approach. Provide a concluding statement, interpreted within the context of the question.
