To examine the distribution, complete the following steps:

1.Create a histogram for AGE. Click on Analyze, Frequencies (select AGE), Charts, and Histograms (select Show normal curve on histogram).

2.How does the distribution of AGE deviate from the theoretical normal curve?

3.Calculate the mean and standard deviation for AGE in this sample, using either the Frequencies or Descriptives procedure.

4.Assuming the distribution of AGE is normal, calculate the number of people who should be 25 years of age or less.

5.Use the Frequencies procedure to construct a table of the percentage of cases at each value of AGE. Compare the theoretical calculation in (c) with the actual distribution of age in the sample.

6.What percentage of people in the sample are 25 years old or less?

Is this value close to what you calculated
