The effects of recent exposure on general-knowledge estimation

Abstract:
Recent exposure to general-information facts creates a tendency to claim that the facts had been known prior to their exposure. In Experiment 1, this "illusory knowledge effect" occurred even when participants did not have to demonstrate their knowledge by recalling part of the fact. In Experiment 2, the effect was found for both true and false facts. These findings suggest that the tendency to claim that recently presented facts had been previously known is caused by their enhanced familiarity. Accounts that would attribute this effect entirely to an underestimation of participants' knowledge of the new facts or to participants' intentional inflation of their prior knowledge states are not supported by these results.

Testing a Claim about Mean: Known Population SD
Estimating a population mean requires the samples to be distributed normally. The data should be collected from the randomly selected samples having no sampling bias. The sample size needed to be higher than 30, and most importantly, the population standard deviation should be already known.
In most realistic situations, the population standard deviation is often unknown, but in rare circumstances, when it...
