You are studying the impact of the number of prior arrests on
sentence length, in months, for a sample of 94 criminal defendants
from the Prince George’s County District Court. The
following frequency distribution represents the number of prior
arrests for your sample of 94 defendants. Note
that, this assignment requires that you calculate the cumulative
frequency, percentage, cumulative percentage, etc….etc.

Please answer the following question using the above data
set:
1. What is the predicted population standard deviation?
2. Draw and superimpose a bell curve and label your data up to 3
standard deviation units from the mean. Use the standard deviation
for the data set.
3. Is the above data set more or less variable than a data set
that has a standard deviation of 7.25?
4. Is the...
