Question:

Homicide rate (homicides per 100,000 population) for each of the 50 states appeared in the 2010 Statistical Abstract (www.census.gov). A frequency distribution constructed from the 50 observations is shown in the following table:

a. Calculate the relative frequency and density for each of the seven intervals in the frequency distribution. Use the computed densities to construct a density histogram for the variable x = homicide rate for the population consisting of the 50 states.

b. Is the population distribution symmetric or skewed?

c. Use the population distribution to determine the following probabilities.
