Question
Information Use the following information for Questions 1 -3 To test whether male or female MSU undergrad students have a greater tendency to feel stressed during finals weeks, we randomly sampled 200 current MSU undergraduate students (100 men and 100 women). From our sample, we found that 89 of our 100 men and 77 of our 100 women answered as feeling stressed during finals weeks. What would the value of the observed difference in proportions (men women) be for this study? 0.12 -1.66 -0.12 1.66 In a simulation test for the difference in proportions, where would the distribution be centered ? Explain. At 1, because we assume there is no difference in true proportion of male undergrad MSU students who feel stressed during finals week and the true proportion of female undergrad MSU students who feel stressed during finals week At the sample difference in proportions, because we assume there is a difference in true proportion of male undergrad MSU students who feel stressed during finals week and the true proportion of female undergrad MSU students who feel stressed during finals week At 0.5, because we assume there is no difference in true proportion of male undergrad MSU students who feel stressed during finals week and the true proportion of female undergrad MSU students who feel stressed during finals week At zero, because we assume there is no difference in true proportion of male undergrad MSU students who feel stressed during finals week and the true proportion of female undergrad MSU students who feel stressed during finals weekExplanation / Answer
Answer - 1:
Observed difference in proportions = 89/100 - 77/100 = 0.89 - 0.77 = 0.12
Option A is correct.
Answer - 2:
In a simulation test, the distribution will be centered at 0.
Option D is correct.
