Pat scores a 76 and Chris scored a 94. What percent of individuals would score between Pat and Chris? 65%. A normal distribution of scores has a standard deviation of 10. Find the z-scores corresponding to each of the following values: A score of 60, where the mean score of the sample data values is 40. Z=2. A score that is 30 points below the ...

The proportion of observations that are between two give z-scores. The value with a given proportion of observations above or below it (inverse Normal). Use a table of values for the standard Normal curve to find the proportion of observations in any region given any Normal distribution (i.e., given raw data rather than z-scores).

Students will investigate the properties of a normal curve and the standard normal distribution. They will transform normally distributed data to standard normal scores using z-scores transformations in two problem contexts. The activity also introduces how percentiles are determined using a standard normal table or by using a calculator.
