Directions: Formulate the null and alternative hypothesis in a statement form. Identify whether it s one-tailed or two-tailed. If the hypothesis is one tailed, identify its direction whether it is left or right. If two tailed, write both sides. 1. A teacher in Math announced that the mean score of Grade 9 students in the first quarterly assessment in Mathematics was 89 and standard deviation was 6. One student, who believed that he mean score was less than this, randomly selected 30 students and computed the mean score. 2. An academic organization claimed that Grade 11 students' study time is at most 240 minutes
