INSS 2304 Homework Assignment #1 Name:___Jose Corral____________________ __ Instructions: 1) Show all of your work. 2) Round your final answers to 2 decimal places. 1. On September 11, 2001, terrorists flew two hijacked airplanes into the World Trade Center (WTC) in lower Manhattan in New York City (NYC), destroying both towers of the WTC. As of August 16, 2002, a total of 2,726 death certificates related to the WTC attacks had been filed. 1) Of these 2,726 decedents, 2,103 (77%) were males and 623 (23%) were females. What is the mode for gender? (2 points) Mode for gender = Male More males than female so males were more frequent. 2) The median age for these decedents was 39 years. How do you interpret this? (2 points) By setting up a frequency graph to set the ages from youngest to the oldest of the people that died. Then you can see how many people fit into each age group. Afterwards, you can find the median by using the median position formula (n+1)/2= med position. This will show which age is the median along with how many people died that were of that age. N being the different number of ages. 3) Of these 2,726 decedents, 1,659 (61%) were non-Hispanic white males, 407 (15%) were non-Hispanic white females, 177 (6%) were Hispanic males, 81 (3%) were Hispanic females, 136 (5%) were non-Hispanic black males, 79 (3%) non-Hispanic black females, 122 (4%) were Asian/Pacific Islander (API) males, and 54 (2%) were API females. What is the mode for the racial/ethnic and sex group? (2 points) After you organize all ethnic groups based on how many there are you can see that the mode for the racial/ethnic and sex group is non-Hispanic white males. Non-Hispanic white males: 1,659 Non-Hispanic white females: 407 Hispanic males: 177 Hispanic females: 81 Non-Hispanic black males: 136
Non-Hispanic black females: 79 Asian/Pacific Islander (API) males: 122 Asian/Pacific Islander (API) females: 54 4) Please see the table attached below (source: http://www.cdc.gov/mmwr/preview/mmwrhtml/mm51SPa6.htm#tab1 ). What is the mode for state of residence? (2 points) Can you get the median? What is it? (2 points) New York is the mode for state of residence due to having the greatest number of deaths at 1,762. Listing them for the median first: Arizona, Delaware, Indiana, Louisiana, New Mexico, Ohio, Tennessee, Utah, Colorado, Floria, Michigan, Missouri, Texas, Maine, Maryland, Virginia, Georgia, Rhode Island, Illinois, New Hampshire, Pennsylvania, Foreign Country, California, Connecticut, Massachusetts, New Jersey, and New York. 28 states listed from least to most deaths. Using the med pos=(N+1)/2 we can find the median state. 28+1=29/2=14.5. This is between Maine and Maryland. Now we can add those and divide them by two like the equation. The median we see is 3.
2. You are asked to study the response time of police departments in Arizona. You collect a random sample of data on the average response time for 55 departments. Your data is presented below. Please answer the following questions:
