Question

In a population of 1000 subjects, 770 possess a certain characteristic. A sample of 40 subjects selected from this population has 24 subjects who possess the same characteristic. What are the values of the population and sample proportions?

Answer 1

0.77,0.60

Explanation:

Given that in a population of 1000 subjects, 770 possess a certain characteristic.

A sample of 40 subjects selected from this population has 24 subjects who possess the same characteristic

To find out sample proportion:

Sample size n = 40

Favourable x = 24

Sample proportion p =
`(24)/(40) =0.60`

To find out population proportion:

Total population N = 1000

Favourable X = 770

population proportion P =
`(770)/(1000) =0.77`
