Assuming that the heights of college women are normally distributed with mean 66 inches and standard deviation 2 inches, what percentage of women are shorter than 72 inches?

  • Statistics -

    Try z-scores:

    z = (x - mean)/sd

    x = 72
    mean = 66
    sd = 2

    Calculate the z-score, then check a z-table for your probability (remember the question is asking "what percentage of women are shorter than 72 inches" when looking at the table).
