A lecturer claims that their course is not too easy and that on average, students score 60%. We want to verify this claim by performing a single tailed test with the null hypothesis =60% vs the hypothesis >60%. For this, we take a random sample of 50 students. Decide on the appropriate test statistic and compute the corresponding (positive) bound of the critical region for a single tailed test at the 98% level. Give the result to four decimal places.
