Suppose in a large City A the average
number of homicides is 98 per year, with a standard deviation of
25. In a midsized City B the average number of homicides is 44,
with a standard deviation of 17. In 2000, City A had 119 homicides
while City B recorded 62 homicides. Assuming both distributions are
normal, calculate the following using the Table of Proportions of
Area under the Normal Curve (z- table):
If City B had 33 homicides in 1998, what percentage greater were
the homicides in 2000?
