Question

Living with AIDS The table gives the number of people diagnosed with AIDS/HIV in 2010 in the five states with the largest number of causes, as well as the District of Columbia, as reported by the U.S. Centers for Disease Control and Prevention (CDC). It also shows the population of those regions at that time from the US Census Burea. Find the number of people diagnosed with AIDS/HIV per thousand residents in each region, and rank the six regions from highest rate (rank 6) Compare these rankings (of rates) with the ranks of total number of cases. If you moved to one of these regions and met 50 random people, in which region would you be most likely to meet at least one person diagnosed with HIV? In which of these regions would you be least likely to meet at least one person with HIV?

State	HIV	Population
New York	192,753	19,421,005
California	160,293	37,341,989
Florida	117,612	18,900,773
Texas	77,070	25,258,418
New Jersey	54,557	8,807,501
District of Columbia	9,257	601,723

Answer 1

State	HIV	Population	rate	RANK
New York	192,753	19,421,005	9.924975561	2
California	160,293	37,341,989	4.292567276	5
Florida	117,612	18,900,773	6.222602642	3
Texas	77,070	25,258,418	3.05125998	6
New Jersey	54,557	8,807,501	6.194379087	4
District of Columbia	9,257	601,723	15.38415517	1

Here we calculated the rate that is, the number of people diagnosed with AIDS/HIV per thousand residents in each region as

no. of individuals diagonised with HIV/AIDS - * 1000 total population

Thus district of Columbia has the highest rate.  So, If you moved to this region (District of Columbia) and met 50 random people, you would most likely meet at least one person diagnosed with HIV.

While,Texas has the lowest rate. So, if you moved to this region (Texas) and met 50 random people, you would least likely meet at least one person diagnosed with HIV.
