You run a study on eyewitness memory testing people's ability to identify a suspect from a lineup of faces that are presented all at once
You run a study on eyewitness memory testing people's ability to identify a suspect from a lineup of faces that are presented all at once (i.e., simultaneous) or one by one (ie, sequential). If you were to repeat this experiment 1000 times, the blue distribution below represents the population of difference scores li.e., difference in accuracy between the conditions in your experiment) if the null hypothesis is true. Under the null distribution, the mean difference between the simultaneous and sequential conditions in your experiment is O and any differences between the two conditions observed on any given experiment is due to chance or random error variance. The yellow distribution represents the population of difference scores if the null hypothesis is false. You do not know what the mean of this distribution is, so you infer it based on the difference you observe in the sample you've collected. C D B A If you were to reduce your alpha level you would be making it harder to falsely reject the null hypothesis in your experiment (ie, a Type I error or false alarm), but what else would happen? Select all answers that apply. (2 pts] O] statistical power would also increase I the mes rate (Type II error, B) would also increase [ the hit rate (D) would also decrease " the comrect ejection rate [() would also decrease
