Recall the (make-believe) matched-pairs investigation of the effect of drinking two beers on reaction time in a driving simulator. We set a significance level of 5% and tested the following hypotheses. : Drinking 2 beers has no effect on reaction time. : Drinking 2 beers slows reaction time. We defined as the mean of the difference in reaction time (before minus after) for all students at this college after drinking two beers. We rewrote the hypotheses in terms of . : : Flag question: Question 1 Question 1 5 pts Identify the type I error. Group of answer choices Researchers conclude that drinking 2 beers slows reaction time, and this is true. 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. Researchers conclude that drinking 2 beers does not significantly slow reaction time, but this is not really true. Flag question: Question 2 Question 2 5 pts The significance level is 5%. The P-value was 0.014. What is the probability of a type I error for this hypothesis test (assuming that the null hypothesis is true)? Group of answer choices 0.05 0.014 It is impossible to tell from the information given
