what is percentage of scores between37.5 and 39

  1. JJ

    We need to know some other information. Like the mean and standard deviation for these scores.

    subtract the mean from 37.5 and divide by the standard deviation to get a z-score.

    do the same for 39.

    Use a z-table to find the percentage of scores that will be between the two numbers.
