Let's Practice ACTIVITY 1 Directions: Find the critical value of each of the following. Write your answer on the appropriate column. Type of test Level of Significance Degrees of Freedom Critical Value (a) (df) Right-tailed 0.05 24 Left-tailed 0.05 13 Two-tailed 0.05 14 Right-tailed 0.01 12 Left-tailed 0.01 10 Two-tailed 0.01 6 11 ACTIVITY 2 Directions: Given the problem, identify the appropriate rejection region for a given level of significance. It is claimed that the average age of teenagers who play Mobile Legend in a certain barangay is 14 years. A group of research students selected a random sample of 25 teenagers. The computation of their ages resulted to an average of 16 with a standard deviation of 9 years. Does this mean that the average age of working student is different from 14 years? Use 0.05 level of significance and assume normality in the population. How do you find the activity? Can you now illustrate the rejection region on your own
