Question

Greenville County, South Carolina, has 461,299 adult residents, of which 59,969 are 65 years or older. A survey wants to contact residents.(a) Find the proportion of Greenville county adult residents who are 65 years or older. (Enter your answer rounded to two decimal places.)

Answer 1

The proportion would be the number of the sample (x) over the population size (n)

Here we have x = 59,969 and n= 461,299

P = x/n = 59969/461299

P = 0.13
