    In reality drinking 2 beers does not have much of an impact on reaction time, but researchers conclude from this experiment that drinking 2 beers significantly slows reaction time.

    Explanation:

    Hypothesis testing is used to test statistical significance of a mathematical proposition. Null Hypothesis is a neutral, no significance stating hypothesis. Alternate Hypothesis is a specific, significance stating hypothesis.

    Null Hypothesis : Drinking 2 beers don't impact reaction time

    Alternate Hypothesis : Drinking 2 beers impact (slows) reaction time

    Type 1 Error is the rejection of an actually true null hypothesis. So, it implies that - In reality drinking 2 beers does not have much of an impact on reaction time, but researchers conclude from experiment that drinking 2 beers significantly slows reaction time.
