What is the incidence of diabetes in Texas? Express your answer in units of per 1000 persons per year

20.73 ≈ 21 persons per year

Step-by-step explanation:

Data provided in the question:

Total population of Texas = 17.7 million

People having diabetes = 1.45 million

Number of new cases of diabetes diagnosed for the first time = 366,921

Now,

the incidence of diabetes in Texas

= [ Number of new cases diagnosed ] : [ Total population ]

= 366,921 : 17.7 million

= 366,921 : 17,700,000

= 0.02073

thus,

the incidence of diabetes in Texas per 1000 persons

= 0.02073 * 1,000

= 20.73 ≈ 21 persons per year
