Answer:
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.
<span>Whitney's explanation of why she got the a- on her science test, that is was a difficult test but a fair one, shows her reasonableness. Her hard work did not mean she deserved a better grade.</span>
