Answer #2

The most important assumption for any significance test is that the data result from a random sample or randomize experiment.

Answer: True

We know that the most of the significance tests requires the assumption of the randomization because if we do not select the data randomly from the population under study, then we cannot get unbiased results for these significance tests. If technique of random sampling do not use for the data collection method, then we cannot infer regarding the population parameter due to bias included in the sampling.
