Historically, the proportion of students entering a university who finished in 4 years or less was 62%. To test whether this proportion has decreased, 120 students were examined and 48% had finished in 4 years or less. To determine whether the proportion of students who finish in 4 year or less has statistically significantly decreased (at the 5% level of signficance), what is the critical value? (please round your answer to 2 decimal places)
