      Using a Graphing calculator to use a Z-table Finding % given bounds (for a non-standard normal) normalcdf( can be used to give you the % between a lower and upper bound for a non-standard normal (i.e. if the mean is not 0 or the standard deviation is not 1) You enter normalcdf(a, b, μ, σ) Where μ is the mean and σ is the standard deviation

      A z score of 0 means 50% of scores fall below the mean score. So we still need to find another 33% of the area under the standard normal curve (50% + 33% = 83%). In this case, we can work backwards or 100% - 83% (or 17%) to find the area beyond that point. The z score is .95 (area of 17.11% beyond).

      For example, we find by looking where the area is 0.1 (or as close as possible): Since the closest area to 0.1000 is 0.985 on the table, we find the z-score (for the left tail) to be -1.29 (add the 0.09 at the end of the -1.2). Since we are interested in the positive value, we conclude BUT, there is a MUCH EASIER way to find these values using ...
