Assume that the distribution of scores in a Math test is normal, with μ = 100 and σ = 10. What is the probability that:
- A score is 125? (Hint: find the z-scores of the real limits and the difference between their probabilities.) (4 pts)
- A score is below 80? (4 pts)
- A score is between 125 and 80? (4 pts)
