You are presented with a dataset that is a 25% simple random sample of a database containing all current members of Congress. Variables include gender, tenure, -home state, and age. You have access to the entire database. What can you do to validate that the sample taken is truly random

Compare the distribution of gender and home state, as well as the average tenure and age in the sample with that of the entire Congress. All of these values -should be approximately equal
Compute the ratio of the number of rows in the sample to the number of rows in the complete database. If the ratio is equal to 0.25, the sample was taken -correctly.
Identify which state has the greatest number of records in the sample dataset and which state has the greatest number of records in the entire database. If they -match, the sample was taken correctly.
Take your own simple random sample from the entire database and compare the rows with the sample that you were presented. The difference should be minimal.
