4 1 point Suppose we want to estimate the difference in population proportions of UWEC students who have a meal plan for the following two populations: . Population 1: students who live on campus . Population 2: students who live off campus We obtain a 95% confidence interval of (.21, .45) for p1 - p2. What is the interpretation? The proportion of students who have a meal plan and live on campus could be the same as the proportion who live off campus. The proportion of students who have a meal plan and live on campus is smaller than the proportion of students who live off campus by between .21 and .45 The proportion of students who have a meal plan and live off campus is between .21 and .45 The proportion of students who have a meal plan and live on campus is larger than the proportion of students who live off campus by between .21 and .45 The proportion of students who have a meal plan and live on campus is between .21 and .45
