Suppose we have a population of scores with a mean(mu) of 200 and a standard deviation(sigma) of 10. Assume that the distribution is normal. Provide answers to the following questions:

1. What score would cut off the top 5 percent of scores?

2. What score would cut off the bottom 5 percent of scores?

3. What score would cut off the top 2.5 percent of scores?

4. What score would cut off the bottom 2.5 percent of scores?
