To determine which sample size would result in a better representation of data that could use a binomial distribution model, we should consider the ratio of the sample size to the population size. A better representation is typically indicated by a larger sample size relative to the population size.
Let's evaluate the options given:
-
A sample of 1,000 people to represent a population of 11,000
Proportion: -
A sample of 300 people to represent a population of 700
Proportion: -
A sample of 100 people to represent a population of 200
Proportion: -
A sample of 500 people to represent a population of 800
Proportion:
Based on the proportions calculated, we can see that:
- The sample of 100 out of 200 has a 50% proportion.
- The sample of 300 out of 700 has about a 42.9% proportion.
- The sample of 500 out of 800 has a 62.5% proportion.
- The sample of 1,000 out of 11,000 has about 9.1% proportion.
The best representation in terms of sample size relative to population size is:
D. a sample of 500 people to represent a population of 800 (0.625)
This option has the highest proportion of sample size to population size, resulting in a better representation of data that could use a binomial distribution model.
