Question
Consider a random sample of 100 females and 100 males. Suppose 15 of the females are left-handed and 12 of the males are left-handed. We are interested in whether or not the true proportions are significantly different. Finish the sentence: A Type I Error would be made if OA we conclude that there is no difference in the proportions of all males and females who are left-handed, when there actually is a difference. B we conclude that there is a difference in the proportions of all males and females who are left-handed, when there actually is no difference we conclude that there is a difference in the proportions of the 100 males and 100 females who are left handed, when there actually is no difference. Dwe conclude that there is no difference in the proportions of the 100 males and 100 temales who are left-handed, when there actually is a difference.Explanation / Answer
Type I error is associated with the decision of rejecting the null hypothesis when it is true.
Hence,
Option B is correct.
