Directions: Directions: Here's the data about the Math Pretest and Posttest scores of ten (10) Grade 12 students of Bucal National High School. Is there a significant relationship between the pretest and posttest scores in Math? Student Pretest Posttest 1 49 45 32 37 34 39 45 47 41 40 20 40 27 39 32 45 37 41 10 31 481. Compute the value Pearson's r: 2. Interpretation: 3. What linear equation best predicts the posttest given the pretest in Math? 4. If a student made a pretest score of 43 in Math, what grade would you expect the posttest score the student will obtain? 5. Show the line of best fit and its interpretation.A. Directions: A random sample of 10 Grade 7 students has grades in MAPEH, where marks range from 90 (Good) to 98 (Excellent). The general average grade (Gen. Ave. )of all Grade 7 students as of the last 5 years is 95. Is the Gen. Ave. of the 10 Grade 7 students different from the population's Gen. Ave? Use 0.05 level of significance. Student 2 3 4 5 6 7 8 9 MAPEH 10 92 95 95 96 97 98 95 94 Grade 98 92 Given: n=10 cr=0.05 Ho=95 X = sd= 1. Perform hypothesis testing using the Critical Value Approach. 2. Perform hypothesis testing using the P-Value Approach
