You have a score on a national entrance exam of 95. What percentage of people in the population have a score that is lower than yours? (Assume the population mean is 75 and the standard deviation is 10. Use the table I passed out in class.)

    Z = (score-mean)/SD

    Either use the handout or find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability related to the Z score.
