Answer 1

Sampling Error

Explanation:

We are told that 12% of all people are left handed.

Now, from the sampling done, we are told that 16% of them were left handed.

This is a 4% difference.

However, we are told that no mistakes were made in the data collection or data recording.

This means that it is likely the error came from the fact that the 200 people sampled didn't reflect the total population because the 12% reflects the true population.

Thus, this is clearly a sampling error.
