Im not sure if I have these set up correctly In 2010 Florida

In 2010, Florida had 876,975 gun owners for a population of 10,000,000. What is the gun ownership rate per 1,000 residents? If 62% of the 43,000 students at U of M major in Natural Science, how many students are Natural Science majors? What is the Natural Science major rate per 1,000 students? In 2013, the US murder rate was 6.2 per 100,000 individuals. Given the population of? US is 330,000,000; how many murders were committed?

Solution

Total population = 10,000,000 = 10,000 (1000s)

Gun owners = 876975

Gun ownership rate per 1000 residents = 876975/10000

= 87.6975

------------------------------------------------

Natural science major students are = 43000x62%

= 26660

Natural science major rate per 1000 students = 62/10 = 6.2

c) US murder rate = 6.2 per 100000 individuals

Hence for total of 330,000,000 no of murderers = 6.2x3300 =20460
