Dr. ung hypothesizes that children who practice completing puzzles will score higher on their visual-spatial intelligence than the national average. He randomly selects 20 children (N = 20) to complete daily puzzles for one month. The sample's mean visual-spatial intelligence score at the end of the month was 108. The national average score is 100 (m = 100, s = 15). Does completing puzzles daily lead children to have higher visual-spatial intelligence? Answer Questions Below 1: Identify your null and alternative hypotheses. Ho: HA: I 2. Directional or non-directional? One or two-tailed? 3. Whatmwill you use? 4. What does that mean about where the region of rejection is? 5. If mfalls in the region of rejection, what does that Wthe likelihood of getting that value by chance alone? 6. Calculate your m. 7. Will you reject or fail to reject the null hypothesis? Why? 8. Is the probability of getting your mgreater than or less than .05? How do you know? 9. What conclusion can you make regarding the research question? (Specifically, did kids who practiced puzzles have significantly higher visual-spatial intelligence than the national average?)
