Question

if there are 5,200 registered voters are randomly sampled, which statements are true of a sample of 30 voters? check all that apply. the sample size is too small and will show a large variation. the sample size is too small and can lead to false inferences. this is an invalid sample because it randomly chooses voters. a larger sample will give more reliable information. the sample size is too large to make inferences.

Explanation:

A sample size of 30 from 5200 registered voters is relatively small. Small - sized samples can have large variations and may lead to false inferences. Larger samples generally provide more reliable information. Random sampling is a valid sampling method. And a sample size of 30 is not too large for making inferences.

Answer:

The sample size is too small and will show a large variation.
The sample size is too small and can lead to false inferences.
A larger sample will give more reliable information.
